Updated for 2026. A level coach sleeps better, drains tanks cleaner, and is easier on the fridge and doors. This guide helps you choose RV leveling gear by use case: interlocking stackable blocks for most sites, drive-on levelers when you want faster side-to-side correction, and the wheel stabilizer that belongs on tandem axles after you are already level.
How we ranked these
- Interlock and stack guidance: kits that nest cleanly and publish a sane max stack height.
- Load and job fit: tire lift, jack pads, or both — without treating blocks like magic under any height.
- Kit completeness: bag, top/cap, or carry handle so the set survives real storage bays.
- Setup speed vs precision: stackable inch steps versus drive-on curved levelers.
- Dual-axle reality: leveling blocks get you flat; an X-style chock cuts fore-aft rock afterward.
We are not ranking scrap lumber piles or no-name thin blocks with no clear kit story. Start from the best RV accessories shortlist mindset: buy once, store clean, use the same system every arrival.
Quick picks
| Gear | Best for | Why it makes the list |
|---|---|---|
| Tri-Lynx Lynx Levelers 11-pack | Most owners’ primary block kit | Interlocking USA-made set with cap and bag — the default stackable pick |
| Camco Heavy Duty 10-pack | Budget stackable kit | Classic yellow interlocking blocks with storage bag |
| Camco FasTen 10-pack | Owners who want a carry handle | Interlocking blocks plus twist T-handle for bay storage |
| Andersen Camper Leveler 2-pack | Faster drive-on side-to-side leveling | Curved levelers with rubber mats and duffel — ramp-style workflow |

1. Tri-Lynx Lynx Levelers 11-pack — best overall stackable kit
Best for: Travel trailers, fifth wheels, and motorhomes that need modular height under tires and/or jacks. Skip if: you only want a drive-on curved leveler and never stack blocks.
This is the interlocking kit already trusted on our accessories shortlist: ten Lynx blocks, a Lynx Cap top, and a nylon bag. Build a pyramid or stepped stack, drive on carefully, then chock. The same blocks work under stabilizer and tongue jacks when you need a clean pad instead of random scrap wood.
Pros: Modular interlocking design; includes level-top cap and bag; long track record as the “orange Lego” system many parks already recognize.
Caveats: Soft ground can still swallow a tall stack — add flex pads. Respect manufacturer stack guidance; taller is not always safer.
2. Camco Heavy Duty Leveling Blocks 10-pack — best budget stackable kit
Best for: Owners who want a proven yellow interlocking set without stepping up to FasTen. Skip if: you specifically want the FasTen T-handle carry system.
Camco’s heavy-duty 10-pack (model 44505) is the common “buy the yellow ones” answer: interlocking resin blocks, about an inch of lift per nested block, zippered bag. Fine under single or double wheels and under many jack feet when stacked in an approved pattern.
Pros: Easy to find, easy to store, solid everyday kit.
Caveats: Camco’s own guidance caps practical stack height (commonly four blocks) — plan extra kits for dual wheels or steep pads instead of building unsafe towers.
3. Camco FasTen Leveling Blocks 10-pack — best stackable kit with carry handle
Best for: Frequent travelers who care about grab-and-go storage as much as stack strength. Skip if: a basic bagged kit is enough and you do not want another block ecosystem.
FasTen keeps the interlocking idea and adds a twist T-handle that locks the stack for carrying. Same campsite jobs as classic Camco blocks — tires, tandem axles, tongue and stabilizer jacks — with cleaner bay manners. Stay inside the published max stack height (FasTen calls out roughly 4½ inches).
Pros: Integrated handle; interlocking stack; Made-in-USA FasTen line that plays with other Camco pads/ramps.
Caveats: Still a stackable system — steep side-to-side sites may need more blocks or a drive-on leveler, not a taller single tower.
4. Andersen Camper Leveler 2-pack — best drive-on leveling ramp style
Best for: Side-to-side leveling when you want to drive up to height and chock, without building block pyramids. Skip if: you regularly need more lift than a curved leveler offers, or you mainly need jack pads.
Andersen’s camper levelers are the ramp-style answer in this roundup: place the leveler (mats help on hard pads), drive until the bubble is happy, chock, done. This 2-pack kit includes rubber grip mats and a duffel — the version that makes sense for dual-axle trailers that lift one side at a time.
Pros: Fast precision at small increments; less “how many blocks?” guesswork; mats reduce skating on slick pads.
Caveats: Lift range is finite (Andersen’s camper leveler class is about ½–4 inches). Not a replacement for interlocking blocks under jacks. Confirm tire diameter / trailer weight guidance on the listing for your rig.
5. BAL X-Chock — best wheel stabilizer companion (tandem axles)
Best for: Dual-axle travel trailers and fifth wheels that still rock fore-aft after the coach is level. Skip if: you have a single-axle trailer — X-Chocks need a tire pair to push against.
Leveling blocks fix slope. X-Chocks fix movement between tandem tires. The BAL pair (28012) wedges between the tires with the included ratchet so the axles quit shifting when people walk inside. Install after you are level and chocked for roll; remove before you pull out.
Pros: Noticeable cut in trailer rock; USA zinc-coated steel kit with wrench; fits relatively tight tire gaps.
Caveats: Companion gear, not a leveling system. Measure your tire gap; triple-axle layouts may need a different approach.
6. Camco Universal Flex Pads — best soft-ground accessory
Best for: Grass, gravel, sand, or any pad where plastic blocks or jack feet sink and tilt. Skip if: you only ever park on concrete and already run wide jack pads.
Flex pads are the unglamorous upgrade that saves cracked blocks. Drop them under Lynx/Camco stacks or under stabilizer/tongue jacks so the load spreads instead of punching a hole. This Camco 2-pack (44600) is sized for common 8½-inch block footprints.
Pros: Works with multiple block brands; recycled rubber flex instead of brittle thin discs.
Caveats: Pads add weight/bulk; buy enough pieces for every corner you actually use.
Buyer’s guide: how to choose RV leveling blocks
Stack height
Measure first. A bubble level (or a graduated stick-on level when you can find one in stock) tells you how many inches the low side needs. Build only that height — plus a clean drive-on ramp profile — instead of stacking to the moon. Most interlocking kits publish a max nested height; treat that as a hard limit.
Load rating and contact patch
Manufacturer load claims assume the blocks are used as directed on reasonably firm ground. Soft soil concentrates load on edges and cracks blocks. Widen the footprint with flex pads or boards under the stack when the pad is mush.
Interlocking blocks vs drive-on ramps
Interlocking blocks win on versatility: tires, jacks, odd heights, odd sites. Drive-on curved levelers win on speed for moderate side-to-side correction. Many owners eventually carry both — blocks in the bay, Andersen-style levelers for the sites that only need a couple inches.
Chocks vs blocks
Blocks change height. Chocks stop roll. X-style stabilizers (like BAL X-Chock) reduce tandem-tire shift after you are level. Use all three jobs correctly: level → wheel chock for roll → X-Chock for rock on dual axles → then drop stabilizer jacks onto pads.
Single vs dual axle
Single axle: usually one stack under the low-side tire (or a drive-on leveler), plus tongue jack fine-tuning front-to-back. Dual axle: plan enough block width/length for both tires on the low side, or use a drive-on leveler per axle as the manufacturer recommends — then add X-Chocks between the tires. Dual wheels (duallies) often want wider FasTen-style boards or carefully built double stacks so each tire is supported.
FAQ
How many leveling blocks do I need?
One 10- or 11-pack is the minimum for many single-axle trailers on mild sites. Dual-axle or chronically unlevel parks are easier with a second kit so you are not stealing jack pads to finish a tire stack.
Can I use leveling blocks under stabilizer jacks?
Yes — that is a normal use for Lynx/Camco-style blocks — but jacks stabilize; they are not meant to throw the coach up in the air. Level on the tires/suspension first, then stabilize onto pads.
Are Andersen levelers better than Lynx Levelers?
Different jobs. Andersen-style drive-on levelers are faster for moderate side-to-side lift. Lynx-style interlocking blocks are more flexible for height, jacks, and weird sites. Plenty of rigs carry both.
Do I still need wheel chocks if I have X-Chocks?
Yes. X-Chocks stabilize tandem tires against each other; conventional chocks still guard against roll on a grade.

Pair leveling gear with the rest of the arrival kit on our best RV accessories list. After the coach is planted, a quality TPMS watches the tires you just trusted on blocks. At the pedestal, use a proper surge protector / EMS before you power up.
Final thoughts
Most owners should start with Lynx Levelers (or Camco Heavy Duty if you want the yellow budget kit), add flex pads for soft ground, and — on tandem axles — finish with X-Chocks. If arrivals are always a side-to-side fight on mild grades, step up to an Andersen drive-on leveler kit instead of building ever-taller block towers.
