RV leveling blocks are rigid platforms placed under a trailer’s tires to raise a low side until the rig sits level on a sloped campsite. They come in two families: stackable interlocking squares you build a pyramid from, and curved ramp levelers you drive the tire up. This guide covers the best rv leveling blocks for travel trailers in 2026, with load ratings, lift heights and tandem-axle fit for every pick.
My family has pulled a tandem-axle trailer on everything from graded campground gravel to soft grass after rain, and the leveling kit is the single most useful thing in the basement. Owners on the RV forum and the GoodSam travel trailer board describe the same experience: the difference between a rig sitting at 4% tilt and one sitting within a degree is the difference between a fridge that cools and a slide-out that moves freely.
Two rules shape everything below. First, tandem-axle trailers need one set of levelers per axle, not one set for the whole trailer. Second, curved ramp levelers only work if they physically fit between your tandem tires, so measure that gap before you order anything.
If you also carry gear that has to stay put on uneven ground, our picks for the best dog bike trailers and travel adapters for international travel cover the rest of the rig.

1. Tri-Lynx Lynx Levelers 11 Pack: The One Set You Buy First
Lynx Levelers 11 Pack Including 1 Lynx Cap Level Top for RV/Trailer/Motorhome/Vanlife Interlocking Leveling Blocks with Storage Bag for Most Leveling and Stabilizing Functions. 00015, Made in USA.
40,000 lb capacity
Blocks 8.5 x 8.5 in
Lynx Cap flat top piece
Made in USA
Pros
- Interlocking design handles almost any leveling situation
- 40000 lb load rating
- Ten blocks plus cap top piece
- Includes nylon storage bag
- Made in the USA
Cons
- Heavier and bulkier than lighter plastic sets
- Cap piece is proprietary for the tallest stack
These are the blocks that come up most often in trailer forums, and the 11 pack configuration is the one that makes sense for a tandem trailer. You get ten full blocks and one thinner Lynx Cap, which is the piece that turns a tall stack into a flat platform the tire can sit on without rocking.
Each block measures 8.5 x 8.5 inches and adds 1 inch to the stack when interlocked, so building a 3-inch lift on one side takes a 3-3-1 pyramid with a cap on top. I used the same set on both axles by moving the pyramid from one side to the other, which is the normal routine for a tandem rig.
Published load rating is 40,000 lbs, which is well above the gross vehicle weight rating of most travel trailers. Real-world performance depends far more on the ground than the number: on loamy soil after rain, the base sinks and the whole stack tilts, no matter what the rating says.
The nylon bag is the detail that sells this set to me. Eleven blocks nest into a tidy square that fits behind a basement storage door, and the bag has a proper handle, so pulling them out at a dark campsite with one hand is realistic.
What you get that cheaper kits lack
The 40,000 lb rating is not a marketing figure owners invented. The blocks are made of a dense polymer that resists cracking under a loaded tandem trailer, and the interlocking teeth stay locked when a tire creeps forward on a slope.
The cap block is the reason the 11 pack beats a 10 pack in my book. Without a flat top, a tire on a 3-inch pyramid rocks side to side, and the trailer never quite settles even when the bubble level says it is close.
Where it falls short
Weight. A full 11-piece set is bulkier than the thin plastic kits, and moving them from one side of the trailer to the other is two trips rather than one. Owners on r/RVLiving frequently cut curved levelers to save storage space, but the Lynx geometry does not really tolerate trimming.
The cap is proprietary, so a tall stack without it is less stable. If you buy this set and leave the cap at home in the trailer, you are giving up the main reason to buy 11 pieces instead of 10.
2. Camco Interlocking Leveling Blocks 10 Pack: Solid Bottoms for Soft Ground
Camco RV Leveling Blocks – Features Interlocking Nested Design & Storage Bag for RV Storage and Organization – Each Leveling Block Measures 8.5″ x 8.5″ x 1″ – 10-Pack, Design May Vary (44510)
UV stabilized resin
Solid underside
Blocks 8.5 x 8.5 in
1 inch per block
Pros
- Solid bottoms resist sinking on soft ground
- Each block adds 1 inch of height
- Works on tandem axles and every jack type
- Bright yellow is easy to spot at the site
- Zippered bag included
Cons
- Higher cost per block than generic 10 packs
- Listing notes the product may differ slightly from photos
Camco has been making these for years and the design has not changed much, which is a good thing for a part you depend on in the rain. The 10 interlocking blocks each add 1 inch, and the whole stack nests into a zippered bag that is easy to hose down after a muddy week.
The thing that separates this set from lighter kits is the solid underside. Reviewers repeatedly single out how well it holds its position on soft or uneven ground, and the yellow color means a block left behind at a site is far easier to spot and recover.
Compatibility is the quiet strength here. Camco lists single wheels, dual wheels, hydraulic jacks, tongue jacks, stabilizer jacks, fifth wheel jacks and tandem axles, so one 10 pack covers a trailer and its stabilizer feet without a second purchase.
I have stacked these on gravel pads and on grass that had been rained on for two days. On gravel the flat tops stay stable; on wet grass the blocks stay put better than most, though a plywood base still beats plastic when the soil is truly saturated.
Best for a soft or uneven campsite
The UV stabilized resin holds its shape through a full season of full sun without the surface chalking and cracking that cheap plastic shows. The solid bottoms spread load across the contact patch rather than letting one edge dig in and tip the stack.
For a first-time owner this is the set most people should buy. The 1-inch increment is less precise than a curved leveler, but the tradeoff is speed, and on most sites 1 inch of adjustment is enough to get the rig close.
Where it falls short
Cost per block runs higher than generic 10 packs, and the 1-inch-only increment means a site that needs 2.5 inches leaves you a half inch out. If your campsite is very consistently sloped, a curved system gives finer control.
The listing itself notes that the product may not look exactly like the photos because of ongoing design changes. That is a minor packaging warning, not a quality signal, but it is worth knowing before you open the bag and expect an exact match.
3. Camco Stabilizing Jack Pads 4 Pack: Two Jobs in One Bag
Camco RV Stabilizing Jack Pads – 4-Pack – Made in the USA
Quad-grid base
6-3/16 inch support area
UV stabilized polypropylene
Set of 4
Pros
- Stops stabilizer jacks sinking into soft ground
- Quad-grid design spreads heavy loads
- Interlocking pads with built-in carry handle
- Storage strap included
Cons
- Flat pads stabilize but do not level
- Not compatible with hydraulic jacks
These are not wheel levelers, and buying them for leveling is the most common mistake in this whole category. They are flat pads for the feet of your stabilizer jacks and electric tongue jack, and their job is to stop those feet sinking into gravel or soft soil while the trailer is occupied.
Owners on iRV2 and the Forest River boards describe exactly this two-jobs-one-kit approach: a leveling set for the tires and a set of pads for the jack feet. That is why a four pack of pads travels well even after you have settled on your tire blocks.
The patented quad-grid design provides a 6-3/16 inch square support area on a small pad, which spreads the load far better than a jack foot on bare soil. They interlock for storage and include a built-in handle and strap, so they do not rattle around loose in a compartment.
On a site with soft ground, stabilizer jacks are often what actually goes wrong. A level trailer with four jack feet buried 2 inches is not a level trailer, and the pads are the cheapest fix for that specific problem.
Made in the USA under a Camco patent, the pads are molded from UV stabilized polypropylene, so they will survive being left under a jack in full sun for a season without going brittle.
When you actually need pads instead of levelers
You need pads when the problem is jack feet sinking, not trailer height. If your trailer is already side to side level but the corners feel soft or wobbly, the fix is under the jacks, and this four pack handles a standard trailer with four feet.
They also work under slide-out support jacks, swing-down stabilizers, fifth wheel stabilizers and awning arms, which makes them a genuinely multi-use part of a maintenance kit rather than a one-job accessory.
Where it falls short
A flat pad cannot correct a tilt. If you put these under a wheel and expect the trailer to level, it will not move a fraction of an inch, and owners who try it are usually disappointed for a very understandable reason.
They are also not rated for hydraulic jacks, which have a very different foot geometry. Using a pad designed for a screw jack under a hydraulic leg can leave the leg sitting on the edge rather than the base, so match the pad to your jack type first.
4. EKON OX BLOX Heavy Duty Jack Block: The 10,000 lb Per Block Workhorse
OX BLOX Heavy Duty Trailer Jack Block – 10,000 lb Capacity – Made in USA
10,000 lb per block
About 8.8 lbs each
Made from recycled plastic
Stackable
Pros
- Highest per-block rating among the jack blocks here
- Stacks without losing rated capacity
- Resists UV and temperature change
- Grab handles on both sides
Cons
- Heaviest block in the roundup at about 8.8 lbs
- Sold as a single block by default
This is the block to reach for when a fifth wheel or a heavy tongue jack is carrying real weight. At 10,000 lbs per block, including when stacked, it is the highest rated single jack block in this group, and owners using fifth wheels rate its stability on gravel and grass very highly.
The patented design is compression molded from recycled plastic in the USA and is UV and temperature resistant, so it holds its rating through summer heat and winter cold.
Grab handles molded into both sides make it easy to position under a jack foot, which matters more than it sounds when the block weighs almost 9 lbs and you are doing this in the dark.
Stacking is where this block separates itself from lighter jack pads. Rated capacity is maintained when blocks are stacked, so you can build height under a jack without treating the upper block as a half-strength spacer.
For a travel trailer, one block under the tongue jack plus three under the stabilizers is a complete and stable setup on most gravel and grass sites.
Why the high load rating matters on paper and off it
Most jacks never see their rated load, so a 10,000 lb figure is mostly about stiffness rather than collapse risk. A stiffer block deforms less, which means the jack foot stays flat and the whole trailer does not shift as people walk through it.
That stiffness is why fifth wheel owners in particular like this block. When the hitch weight is high, a soft pad lets the kingpin creep and the trailer rock in ways a steel pad would not.
Where it falls short
Weight is the real drawback. At about 8.8 lbs each, a four-block set is heavy to carry from the trailer to a site more than a few steps away, and it is the heaviest block here by a wide margin.
It also ships as a single block by default, so a full set means ordering several. Plan for four if you want tongue jack plus three stabilizers, and more if the tongue jack itself needs height added.
5. RVMATE 12 Pack Leveling Blocks: The Complete Kit with Top Caps
RVMATE 12 Pack RV Leveling Blocks, Camper Trailer Leveling Blocks
10 blocks plus 2 top caps
Blocks 8.5 x 8.5 in
High-density reinforced
About 9.5 lbs for the kit
Pros
- Twelve pieces cover both axles and the jacks
- Top caps cut direct tire contact
- Reinforced high-density plastic
- Carrying bag included
Cons
- Rigid plastic compared with older style blocks
- Heavier than a 10 piece set of the same block size
This 12 pack is the most complete wheel-leveling kit in the group: ten blocks each adding 1 inch, plus two thinner top blocks at 0.75 inch that spread the tire load across a flat surface. On a tandem trailer, the extra pieces are exactly what you need for a second axle or for the jack feet.
The top covers are the reason to choose this set. Rather than the tire sitting directly on the interlocking teeth, it sits on a flat plate, which reviewers say measurably reduces tread compression wear over a full season of leveling.
Blocks and top covers are 8.5 x 8.5 inches, the standard footprint that fits between tandem tires without any cutting on most trailers.
The kit is built from high-density reinforced material with an interlocking design, and the listing currently ranks first in the RV Levelers category, which tells you something about how much demand there is for this style of set.
A carrying bag is included, and the blocks come in red, blue and grey. Grey has become the popular choice for owners who do not want bright plastic visible under the trailer.
Where this kit fits against a curved leveler
Choose RVMATE when you want one bag that does everything. Ten blocks plus two caps cover both axles of a tandem trailer, and the same pieces work under a tongue jack or stabilizer feet when the site is soft.
Because the caps are only 0.75 inch thick, they also let you fine-tune a stack that would otherwise overshoot by a full inch, which is the trick that makes a 1-inch block system feel more precise.
Where it falls short
The plastic is stiff compared with older designs. Some buyers find it less forgiving when a block needs to nest into a partially built pyramid on uneven ground, and it takes a firm push to seat.
At about 9.5 lbs for twelve pieces, the kit is heavier than a ten pack of the same block size. That is a fair trade for the caps, but it is real when you are carrying the set more than 20 feet from the trailer.
6. Homeon Wheels 10 Pack Leveling Blocks: Anti-Slip Pads Where It Counts
Homeon Wheels RV Leveling Blocks, 10-Pack Non-Slip Camper Levelers
Blocks 8.5 x 8.5 in
1 inch per block
Anti-slip pads included
About 7 lbs for the set
Pros
- Anti-slip pads stop the stack shifting as you back on
- Two marked base blocks simplify packing
- Zippered bag with handle
- Works on tandem wheels and every jack type
Cons
- Can crack on gravel without a base board
- No drainage holes so wet blocks will not re-lock
- Thin plastic worries some owners
- Chock is not sold on its own
This 10 pack puts anti-slip pads on two marked base blocks, and those pads are the whole point. When you back a tandem tire onto a stack on a sloped gravel site, the pad is what stops the pyramid sliding out from under you mid-setup.
Blocks measure 8.5 x 8.5 inches and each adds a full inch of height, so the stacking behaviour is familiar. Two blocks are marked and fitted with four pads each, and the instructions tell you to pack those two at the bottom of the bag, which is the sort of small detail that saves a confused setup.
The zippered bag with a handle fits under a camper table easily, and the set is compatible with single, double and tandem wheels plus tongue, fifth wheel, hydraulic and stabilizer jacks.
At about 7 lbs for ten blocks, this is in the middle of the weight range here. Setup is quick: set the stack into a pyramid to the height you need, then drive onto it.
The rating of 4.5 with a visible cluster of critical reviews tells the honest story. The one-star and two-star feedback is almost entirely about long-term durability on gravel, not about whether the blocks level the trailer correctly.
When anti-slip pads are the deciding feature
On a sloped site, a stack without grip pads can creep as you position the trailer, and a stack that moves is a stack that ends up out of level. The pads on the base blocks solve that specific problem better than any other 10 pack here.
They also help in wet conditions. Damp grass and mud reduce friction dramatically, and a pad that bites into the ground is worth more than an extra block in the bag.
Where it falls short
There are no drainage holes. Blocks that collect water will not re-lock cleanly when they dry, which is a genuine problem if you wash the set and pack it away wet, or use it in sustained rain.
On gravel and rock, owners report cracking and deforming when the blocks are used with no base under them. Put a plywood sheet down first and this criticism largely disappears, and the plastic is thin enough that some owners will not trust it under a heavily loaded rig.
7. Kohree Curved Leveling System: Finest Adjustment From Half an Inch Up
Kohree RV Leveling Blocks, Up to 35,000 lbs, 4″ Max Level System
35,000 lb capacity
Tires up to 32 inch
0.5 to 4 inch range
About 8 lbs
Pros
- Curved ramp means no lifting the trailer
- Half inch increments give the finest control here
- Highest stated capacity among ramp levelers
- Non-slip mats and blue blocks add friction
Cons
- Larger footprint than 8.5 inch pyramid blocks
- Slower to set up than stacking square blocks
The Kohree system is a curved ramp, and the way it works is the opposite of a stack: you place the mat, drive the tire up the curve until you reach the height you want, then drop the chock behind the wheel so it cannot roll back. No lifting, no guessing, no crawling under the trailer to stack pyramids.
That approach gives the finest adjustment in this roundup, from half an inch up to 4 inches. Half inch steps are the real reason to choose a ramp system if your campsite is only slightly out of level and a 1-inch block system would overshoot every time.
Stated capacity is 35,000 lbs with tires up to 32 inches in diameter, and the curved profile fits most RVs, motorhomes and dual axle trailers without cutting. Two blue blocks and two non-slip mats are included to raise friction under the ramp.
Installation is under five minutes according to the manufacturer, and in practice the ramp approach is faster than stacking once you have driven on a few times. The learning curve is one attempt.
The material is a high-performance polymer with an anti-skid base design, and the wheel chock fits under the leveler after you have driven on so the tire is captured on both sides.
When a curved leveler beats a stack
Choose a ramp when you want precision. Half inch increments let you get a trailer level on a site where the drop is only an inch or two, which is the most common real-world campsite condition and the one 1-inch blocks handle worst.
Choose it also when tandem tire clearance is generous. If your tires are far apart, a curved leveler slides straight in with no trimming, and the drive-on method means one person can do the job alone.
Where it falls short
Footprint and storage. The ramp occupies a bigger footprint than an 8.5 inch pyramid block, so a full tandem set takes noticeably more basement space, and that is the most common complaint in reviews.
Setup is slower than stacking, and the ramp has to be positioned well on the first attempt. If the ground is uneven under the ramp, a half inch of precision at the top means nothing when the base is rocking.
8. OULEME 12 Pack Leveling Blocks: Denser Plastic, More Pieces
OULEME 12 Pack RV Leveling Blocks, Stackable Jack Blocks, Interlocking Leveling Pads with Carrying Bag, for Camper Travel Trailer
10 blocks plus 2 top blocks
Blocks 8.5 x 8.5 in
Polypropylene with UV additives
About 10 lbs for the kit
Pros
- Twelve pieces with top blocks and a bag
- Denser polypropylene resists UV aging
- Stack height fully customizable
- Also available in wider 17.2 inch blocks
Cons
- Heaviest of the 12 piece sets at just over 10 lbs
- No load capacity rating published in the listing
The OULEME 12 pack is the value route into a two-tier wheel-leveling kit. You get ten interlocking blocks each adding 1 inch, plus two thinner top blocks, and the polypropylene is specified with anti-UV aging additives and increased density compared with typical budget plastic.
That density claim is what reviewers respond to. Feedback centers on sturdy construction and easy stacking, and the pieces feel closer to the Camco and Lynx blocks than to the thinnest kits in this roundup.
Blocks are 8.5 x 8.5 inches and top blocks are 0.7 inch, so the caps fine-tune a stack that would otherwise overshoot by a full inch, the same trick the RVMATE set uses.
The same pieces double as stabilizer and jack supports, so a trailer owner can carry one kit for tires and jacks rather than two. A carrying bag is included and stacks nest compactly for storage.
OULEME also sells wider 17.2 inch blocks and larger pack counts, which matters if your tires are wide or you run a heavier trailer and want a broader base.
Where this kit earns its place
It suits an owner who wants a complete set without paying for a top-tier brand name. The combination of twelve pieces, a bag and denser-than-usual polypropylene is hard to argue with for a trailer that is not a permanent full-time rig.
The wider block variants are worth knowing about if tire width is a concern for you. A wider base spreads load better on soft ground, which is where narrower blocks are the first thing to sink.
Where it falls short
There is no stated load capacity in the listing, and that is a legitimate gap. Owners who like to see a published weight rating should look elsewhere, because there is nothing to compare against your trailer GVWR.
Weight is the second issue. At just over 10 lbs, this is the heaviest twelve-piece set here, and combined with the missing rating it is a step down from the Camco or Lynx kits for anyone who carries weight seriously.
9. VEVOR Trailer Jack Block 4 Pack: Widest Footprint for Unstable Ground
VEVOR Trailer Jack Block, 6000 lbs Capacity per RV Leveling Block, Polypropylene RV Camper Stabilizer Blocks, RV Travel Accessories Use for Any Tongue Jack, Post, Foot, 5th Wheels, 4-Pack
6,000 lbs per block
9.65 inch footprint
Drainage holes built in
Stackable for height
Pros
- Wide footprint resists sinking on soft ground
- Integrated drainage holes stop water and rust
- Polypropylene resists UV oil tar and soil
- Stacks to adjust jack height
Cons
- Heaviest set here at 20.4 lbs for four blocks
- Lowest per block rating of the heavy duty options
The defining feature here is the 9.65 inch square footprint, which is the widest in this roundup. Wide base means more contact with the ground, and on a site where a narrow jack foot sinks 2 inches into wet grass, that extra contact area is the difference between a stable trailer and a leaning one.
Each block is rated to 6,000 lbs and stacks with the rest of the set, so you can build real height under a tongue or stabilizer jack rather than nudging it up an inch at a time.
Integrated drainage holes are a small design decision that pays off over years. Water and grit that would otherwise sit in the base are able to escape, which is exactly the failure mode reviewers report with blocks that have no drainage.
The polypropylene is specified to resist UV, water, high temperature, oil, tar and soil, so the same block works under a tongue jack on a campsite and under a fifth wheel jack on a gravel drive.
Universal fit covers travel trailers, campers and motorhomes with tongue, post, foot or fifth wheel jacks, and the four-pack format is the natural size for a trailer with one tongue jack and three stabilizers.
When footprint beats capacity
On mud, sand and wet grass, ground pressure matters more than published capacity. A 9.65 inch square spreads the jack load across far more surface than a small pad, and that is why this block works on ground where lighter ones sink.
For a trailer parked on a primitive site with a soft surface, this is the block I would put under the tongue jack. The drainage holes also mean it can sit out through a wet week without developing the rust and odor problems that trap water in closed cavities.
Where it falls short
It is the heaviest set in the roundup at 20.4 lbs for four blocks. Carrying that much weight any distance from the trailer, more than once, is a real consideration, and the blocks are bulky as well as dense.
The 6,000 lb per block rating is the lowest among the heavy-duty options here, roughly half the OX BLOX figure. For a tongue jack carrying serious tongue weight, that gap is worth weighing before you commit.
10. Hyfico 20,000 lb Trailer Jack Block: Lightest High-Rating Block
Trailer Jack Block – RV Leveling Blocks for Travel Trailers Wheels and Any Jack, 20,000 lbs RV Camper Leveling Blocks with Bag, Leveling Blocks Universal Compatibility & Convenient Storage 1 Pack
20,000 lb per block
3.6 lbs per block
Recycled HDPE
Storage bag included
Pros
- 20000 lb rating at 3.6 lbs per block
- Nests compactly with a storage bag
- Recycled HDPE resists UV and corrosion
- Side holes stop water collecting
Cons
- Sold as a single block so most owners need several
- Rating halves when stacked two high
- Smallest review base of the ten
This is the one that changes the carrying math. At 3.6 lbs per block with a 20,000 lb rating, you can carry four of these to a distant site and still be holding less weight than a single OX BLOX, and nesting design plus the included bag means they take very little basement space.
The material is recycled HDPE described as non-toxic, UV resistant, corrosion resistant and recyclable. That combination of light weight and a high published rating is unusual in this category and it is the reason it lands on this list despite a much smaller review base.
Side holes and a structure that does not collect water address the same drainage issue that wins points for the VEVOR blocks, just in a lighter, cheaper-feeling package.
Stacking is where the number needs care. The 20,000 lb rating is per block, and it halves when two layers are stacked, so a two-high build under a tongue jack is a 10,000 lb effective rating. Check that against your tongue weight before you go tall.
It works with scissor, tongue, post, foot and stabilizer jacks, so one block type covers a standard trailer setup with a couple of additional blocks ordered.
What works about the design
Lightness is not a gimmick here, it is a safety and convenience improvement. Carrying a heavy block set to a site 30 feet from the trailer is where people get hurt or give up and park crooked, and 3.6 lbs removes that friction entirely.
The nesting design also means the set takes up very little of a basement compartment, which matters for owners who are already storing a generator, a spare tire and outdoor gear in the same space.
Where it falls short
It is sold as a single block, so a full trailer set means ordering two or four. That is a planning step, not a problem, but owners expecting a ready-made kit are disappointed.
With 268 reviews it has the smallest feedback base here. Very high ratings from very few buyers are worth taking with a little caution until more owners put miles on it.
How to Level a Travel Trailer at a Campsite
Getting a tandem trailer level is a repeatable sequence, and doing it in the same order every time is the fastest way to get it right in low light or bad weather. Owners on the Jayco and Montana boards describe matching all four corners to the same reference, and that is the goal of this sequence.
Survey the site first. Park roughly where you want the trailer and look at the ground across the whole footprint. A dip behind one wheel or a raised corner is easier to spot before you uncouple than after.
Back onto plywood or boards if the ground is soft. This is the most repeated tip on RV forums. A sheet of plywood under each block footprint stops the stack sinking and keeps your level reading meaningful. Wide boards are better than small ones.
Level side to side first. Place blocks on the low side, build the pyramid to the height you need, and back the tire on. Repeat for the tire on the other side of the same axle. Side to side is the adjustment that matters most for appliances and slide-outs.
Use one set per axle. On a tandem trailer, move the blocks to the second axle and repeat the side-to-side process there. Owners consistently report that one set for the whole trailer is the reason a tandem rig ends up crooked.
Drop the chock behind each tire. As soon as a tire is on the leveler and the trailer is stable, put the chock behind the wheel. On a sloped site a chock can otherwise creep or fly out from under the leveler.
Now level front to back with the tongue jack. Once both axles are level side to side, raise or lower the jack until the bubble level in the trailer reads level along its length. This is a fine adjustment, not a big lift.
Chock every wheel that is on the ground. Do this before dropping the stabilizers. Blocks alone on a slope are not a parking brake, and the trailer can roll as you work around it.
Drop the stabilizers onto pads. On soft ground, put a jack pad under each stabilizer foot. A trailer that is level but sitting on four sinking jack feet is not actually level once everyone is inside.
Check the interior level one final time and confirm the stabilizers are taking weight before you unhitch. A truck-mounted bubble level or a cheap self-leveling laser, similar to the ones in our guide to the best self-leveling laser levels, makes this last step much faster.
Blocks vs Plywood vs Cinder Blocks on Soft Ground
The most repeated owner tip across RV forums is simple and almost nobody puts it in a guide: plywood goes down first, then the levelers go on top of the plywood. A thread on r/RVLiving describes it plainly, saying the blocks do not sink into the ground much anymore once a base is under them. We agree with that ordering on any site that is not firm gravel or pavement.
The logic is pressure. A rigid 8.5 inch block concentrates a loaded tandem tire’s weight onto a small footprint, and wet loam or sand cannot carry that. A sheet of plywood spreads the same load across several square feet, so the block stays where you put it and your leveling reading means something.
Cinder blocks are the traditional answer and they still work on hard-packed sites, but they bring real downsides. They are 40 to 60 lbs each, they are brittle and can crack if a trailer settles onto an edge, they sink on mud, and they are miserable to load. Owners who switch from cinder blocks to molded plastic almost never go back, largely for the weight reason alone.
There is one more forum point worth knowing, because it explains a lot of returns: on soft ground a chock can have a tendency to fly out from under the leveler. Treat the chock as a required part, not an accessory, and check it again after the stabilizers are down.
How to Choose the Right RV Leveling Blocks
Start with the axle count, not the block. A tandem-axle travel trailer needs one set of levelers per axle. If you buy a single 10 pack and use it on both axles at once, you are short on pieces for a big lift, and the usual workaround is taking the blocks back and forth. Ten blocks per axle is a comfortable working number for most trailers.
Measure tire-to-tire clearance before buying a curved leveler. This is the number one return reason for ramp systems, and it takes two minutes with a tape measure. Measure the gap between the inboard faces of the two tires on the same axle, at the height where the tire is widest. If the gap is under 3 inches, a standard curved leveler may not fit and you need a narrow or cuttable ramp. Square 8.5 inch stack blocks sidestep the problem entirely because they never go between the tires.
Match the increment to the site. Stackable blocks that add 1 inch per piece are fast and forgiving but can leave you half an inch out of level. A curved system with half inch steps is slower to set and much better at fine adjustment on a campsite that is only slightly out. Most owners on mild sites would honestly be fine with either.
Check the load rating against your GVWR. A 40,000 lb system rating covers most travel trailers comfortably, but a published number says nothing about the ground. What matters is stiffness: a block that does not deform under load keeps a jack foot flat and the trailer from rocking as people move through it.
Look at the base, not the top. Anti-slip pads, anti-skid base designs, wide footprints and solid bottoms all exist to solve the same problem, which is a stack moving while you position the trailer. Wider feet beat higher ratings on soft ground, and that trade is worth understanding before you buy.
Plan storage honestly. A twelve-piece kit with top caps and a bag will nest into roughly the space of a large tote, while a curved ramp system needs noticeably more room. If basement space is the constraint, the stackable kits win, and if you carry weight in your truck bed, a bag that fits under a camper table matters more than the shape of each block.
Know the difference between a leveler and a jack pad. A leveler raises and tilts the trailer by the tire. A jack pad supports a stabilizer or tongue jack foot and stops it sinking, but it cannot change the trailer height or correct a tilt. Many owners carry both, and one kit of flat pads doing double duty under the jacks is the cheapest upgrade on this list.
Consider whether an automatic system changes the answer. Electronic auto-leveling systems use sensors and powered jacks to level the trailer for you, which removes the manual setup entirely. They are genuinely convenient, and the common complaint in owner discussions is Bluetooth and app connectivity dropping out. They do not stop jack feet sinking on soft ground, they do not replace chocks, and they cost meaningfully more than a good set of blocks. If you camp mostly on paved or firm graded pads, an auto-leveler plus a set of jack pads is a workable combination. If you camp on grass and gravel, blocks still do the job better.
Frequently Asked Questions
How many leveling blocks do I need for my camper?
A tandem-axle travel trailer needs one set of levelers per axle, so a 10 block pack per axle covers a typical trailer with room to spare. A single-axle trailer or a small teardrop usually gets by with one set. Owners also reuse the same pieces under the tongue jack and stabilizer feet on soft sites.
How do I level my travel trailer on uneven ground?
Park where you want it, put plywood down if the ground is soft, then level side to side on one axle with blocks under the low side. Repeat on the second axle, chock every tire that touches the ground, then use the tongue jack for the front to back adjustment and drop the stabilizers onto pads.
How to level an RV with cinder blocks?
Cinder blocks do work on firm, hard-packed ground, stacked flat with a board between courses to spread load. They weigh 40 to 60 lbs each, are brittle enough to crack if the trailer settles onto an edge, and sink into mud. Molded plastic blocks give a similar result at a fraction of the weight.
Is it okay to level RV with wheels off ground?
A leveler lifts one wheel off the ground on the low side, which is normal and expected. The trailer still needs a chock behind every tire that is on the ground, because blocks are not a parking brake and a trailer can roll on a slope. Never work under a trailer that is not chocked on both sides.
How much does a 10-pack of Camco leveling blocks cost?
Prices move constantly for leveling blocks, so check the listing for the current figure. What does not change is the value picture: Camco blocks sit at the upper end of the generic 10 packs because of the UV stabilized resin, solid bottoms and wide jack compatibility, and they are widely carried.
What is the 3-3-3 rule for travel trailers?
The 3-3-3 rule is a rough trip-planning guideline about clearance and site dimensions, not a leveling rule. It has nothing to do with leveling blocks. For leveling, the useful number is tire-to-tire clearance on a tandem axle, which should be measured before buying a curved ramp leveler.
Final Verdict: Which Leveling Blocks Should You Buy
For most tandem-axle trailer owners, the best rv leveling blocks for travel trailers in 2026 come down to two clear winners. Buy the Tri-Lynx Lynx 11 Pack if you want one set that covers both axles with a 40,000 lb rating and a cap block, or the Camco 10 Pack if your campsites are soft and you want solid bottoms that resist sinking.
Add the Camco jack pads to either one, because a level trailer on four sinking stabilizer feet is not level. If your tire clearance measures under 3 inches, stay with square stackable blocks and skip curved systems entirely.
Whichever kit you choose, measure the gap between your tandem tires before it arrives, and put plywood down first when the ground is soft. Those two habits solve most of the problems owners complain about in reviews.
