Class A motorhomes average roughly 23,000 lbs and range as high as 30,000+ lbs dry weight, while Class C motorhomes typically run 10,000–12,000 lbs, according to RV weight data compiled by Outdoor Troop and industry curb-weight references. That’s two to three times what a typical travel trailer or truck camper weighs sitting on its axles — and it means the plastic wedge chock that came free with a bumper-pull trailer has no business anywhere near a 45-foot diesel pusher. Motorized RVs also chock differently than towables: there’s no hitch to unlatch, no tongue jack to drop, and often a leveling system that needs a chock working alongside it the moment you shut off the engine at a campsite.
Key Takeaways
- Class A motorhome tires commonly run 22–24.5 inches in diameter (some diesel pushers spec 22.5-inch commercial truck tires), well beyond the 26-inch ceiling of many towable-trailer chocks.
- Look for a GVW (gross vehicle weight) rating, not just a tire-diameter spec — a 30-foot Class C and a 45-foot diesel pusher can differ by 20,000+ lbs of axle load.
- Motorhomes need chocks for parking stability at a campsite, not for unhitching, so placement happens after leveling, on all wheel positions the leveling system doesn’t already lift.
- A wheel chock and a leveling block solve different problems and most Class A/C owners carry both, used together at nearly every stop.
- Solid rubber or reinforced polymer chocks resist crushing under sustained heavy axle loads far better than hollow or thin-wall plastic designs.
Why Motorhome Wheel Chocks Are a Different Category
Shop for “RV wheel chocks” and most of what comes up is sized for travel trailers: tires in the 13–16 inch wheel / 24–26 inch overall diameter range, with GVW claims that top out around 4 tons (8,800 lbs) per axle position. That’s fine for a tandem-axle bumper-pull trailer. It is not fine for a motorhome, where a single rear dual-wheel position on a Class A chassis can be carrying 8,000–10,000 lbs by itself, and the tires themselves are frequently 22.5-inch commercial truck sizes shared with delivery trucks and small buses rather than anything you’d see on a car-hauled camper.
Two numbers matter when you’re sizing a chock for a motorhome:
Tire diameter and width. Class C motorhomes built on a cutaway van or pickup chassis (Ford E-450, Chevy 4500/5500) typically run 19.5–22.5 inch commercial-rated tires. Class A gas coaches usually sit on 22.5-inch tires; Class A diesel pushers on a raised rail chassis often run the same 22.5-inch commercial tire used on semi-trucks, sometimes with dual rear wheels that need a chock wide enough to seat against both tires evenly, not just the outer one.
Weight rating. A chock’s GVW rating describes how much sustained weight the chock can resist before it deforms, cracks, or squeezes out from under the tire — not how much weight sits on top of it briefly. Class A curb weights run from about 20,000 lbs for a smaller gas coach up toward 35,000–40,000 lbs GVWR for a large diesel pusher with slide-outs and full tanks. A chock rated for “up to 4 tons” (8,800 lbs) is undersized for most Class A applications and only adequate for the smaller end of Class C.
Chock + Leveling Block: Two Jobs, Not One
On a towable trailer, a wheel chock is often the only thing keeping the rig from rolling once it’s unhitched. On a motorized RV, the parking brake and transmission (park pawl on gas coaches, or an air-actuated parking brake on many diesels) are doing the primary holding job. The chock’s role shifts to backup security — insurance against a parking brake that slips on a grade, or against movement while you’re using an automatic or scissor-style leveling system. That’s why motorhome owners frequently pair a wheel chock with a leveling block (our guide to the best leveling blocks covers stack blocks vs. curved ramps in detail): level first with the blocks or built-in hydraulic jacks, then chock the wheel that’s still resting on pavement or dirt to stop any roll while you’re hooked up and stationary for days. Some products, like the Andersen Camper Leveler below, combine both functions into a single drive-up ramp.
If you’re towing a smaller trailer or truck camper instead, the sizing math above doesn’t apply the same way — see our guide to the best camper wheel chocks for tandem-axle and single-axle towables, where X-chocks that reduce side-to-side rocking are often more useful than a straight block chock.
The Best RV Wheel Chocks Worth Buying
These six picks span the range from budget single chocks sized for smaller Class C rigs up to extra-large sets built for 45-foot diesel pushers, plus one pick for the towed vehicle behind your coach.
1. Andersen Hitches Camper Leveler and Wheel Chock
Best for: drive-up leveling and chocking in one motion on Class A and Class C rigs with tires up to 32 inches.
The Andersen Camper Leveler is technically a leveling ramp, but its curved design doubles as a wheel chock once you’ve driven up onto it — the RV’s own weight locks the tire against the ramp’s stop. It’s rated to 30,000 lbs GVW and fits tires up to 32 inches in diameter, comfortably covering the 22.5-inch commercial tires common on Class A coaches. A single unit runs about $55; the 2-piece kit with a carry bag runs around $78. The tradeoff versus a dedicated chock is that you need to drive onto it precisely, which takes a little practice compared to just kicking a block chock against a tire that’s already parked.
2. AFA Tooling Extra Large Wheel Chocks (4-Pack)
Best for: chocking every wheel position on a heavy diesel pusher rated up to 10 tons GVW.
AFA Tooling’s extra-large chocks are rated to 10 tons (20,000 lbs) GVW, roped together in a set of four so you can double them up on a single dual-wheel position for extra holding force on the steepest campsite pads. Steel tie-off handles make them easy to retrieve without bending down to grab a rubber block covered in gravel. Pricing runs around $42 for the 4-pack, making this one of the better values for owners of full-size diesel pushers who want a chock at all four corners rather than just the rear.
3. Camco 44492 Super Wheel Chock
Best for: budget-friendly single chocks sized for tires up to 29 inches.
Camco’s standard trailer chocks (44412, 44414, 44470) top out around 26 inches of tire diameter — too small for most motorhome front and steer tires. The Super Wheel Chock (44492) steps up to a 29-inch tire diameter rating in the same durable UV-stabilized plastic construction, at roughly $21.65 each. It’s a reasonable middle-ground pick for a Class C on a 19.5–22.5 inch commercial tire, though owners of larger Class A coaches on true 22.5-inch dual tires should size up to one of the rubber or extra-large options above.
4. MaxxHaul 70472 Solid Rubber Wheel Chock (2-Pack)
Best for: all-weather solid rubber holding power in a compact footprint.
At 8″ x 4″ x 6″ per chock, the MaxxHaul 70472 is molded from solid rubber rather than hollow plastic, which matters for sustained loading — a motorhome can sit parked on the same chock for a week or more at a campground, and solid rubber resists the slow crushing and permanent deformation that thinner plastic chocks can develop under that kind of continuous weight. A built-in handle keeps retrieval easy. The 2-pack runs around $16–$20 depending on retailer, making it one of the better values per pound of holding capacity for mid-size Class C and smaller Class A coaches.
5. ROBLOCK Solid Rubber Wheel Chocks (2-Pack, GVW up to 4T)
Best for: Class C and smaller Class A motorhomes under roughly 8,800 lbs of axle load.
ROBLOCK’s solid rubber chocks are rated to 4 tons (8,800 lbs) GVW with a wide 8.6″ x 3.7″ x 4.7″ footprint that resists tipping on uneven campsite pads better than narrower designs. That rating puts it at the smaller end of what’s appropriate for a motorhome — fine for a compact Class C cutaway van, undersized for a full-size diesel pusher. Priced around $15–$20 for a 2-pack, it’s a reasonable pick if you’ve confirmed your coach’s actual per-axle weight falls within its rating rather than assuming based on overall GVWR.
6. Performance Tool W41001 Solid Rubber Wheel Chock
Best for: chocking a towed “dinghy” car or tow vehicle alongside your motorhome.
Motorhome owners have a wheel-chock problem towable-trailer owners don’t: many Class A and larger Class C rigs tow a separate car (a “dinghy” or “toad”) behind the coach, and that car needs its own, smaller chock sized for passenger-car tires rather than motorhome-scale rubber. The Performance Tool W41001 is a compact, 5-lb solid rubber chock with a 7.5-inch wheel contact area, starting around $12.95 — not a substitute for the RV’s own chocks, but a sensible second set to carry for the vehicle you’re towing.

How to Chock a Motorhome at a Campsite
The order of operations differs from a towable trailer, where you typically chock before unhitching. On a motorhome:
- Park and set the parking brake first, keeping the transmission in park (or engaging the air parking brake on a diesel with an air system).
- Level the coach using leveling blocks or the built-in hydraulic/electric jacks — see our leveling blocks guide for stack-block vs. curved-ramp tradeoffs, and our RV stabilizing jack guide if you’re using scissor jacks rather than hydraulics.
- Chock the wheel diagonally opposite the direction of any slope, and add a second chock on the downhill side of a rear dual-wheel position if you’re parked on any meaningful grade.
- Leave stabilizing jacks doing exactly that — stabilizing, not lifting weight off the tires — since jacks aren’t rated to bear the coach’s full weight the way the tires and chocks are.
Frequently Asked Questions
Do I need different chocks for the front and rear of a Class A motorhome?
Not usually different products, but check your coach’s front vs. rear tire sizes — some Class A chassis run a smaller steer tire than the rear duals. One chock model rated for your largest tire diameter will fit the smaller ones too, so buying to the largest tire on the coach is the safer default.
Can I use a towable-trailer wheel chock on my motorhome?
Only if it’s rated for your coach’s actual axle weight and tire diameter. Many trailer chocks cap out at 26 inches of tire diameter and 4 tons GVW, which is undersized for most Class A coaches and the larger end of Class C. Check the spec sheet rather than assuming “RV” on the packaging means it fits a motorhome.
Do I still need a chock if my motorhome has automatic leveling jacks?
Yes. Leveling jacks stabilize the coach against rocking; they’re not designed or rated to be the sole thing preventing the vehicle from rolling. A chock backs up the parking brake, which is the system actually responsible for holding the coach in place.
How many chocks does a Class A motorhome need?
Two is the practical minimum — one at a rear wheel position, ideally on the downhill side if the site has any slope. Owners who frequently camp on unlevel pads often carry four so they can chock both rear positions plus a front tire on steep sites.
What’s the difference between a wheel chock and the leveling blocks I already carry?
A leveling block raises one side or corner of the coach to make the floor level; a wheel chock stops the tire from rolling once you’re parked and leveled. They solve different problems and most motorhome owners use both at nearly every stop — level first, chock second.
The Bottom Line
A motorhome’s tires and curb weight put it in a different category from a towable trailer, and the wheel chock has to match: look for a GVW rating that covers your coach’s actual axle load (not just its overall GVWR) and a tire-diameter spec that accounts for 22.5-inch commercial tires rather than the 24–26 inch range sized for campers. The Andersen Camper Leveler and the AFA Tooling Extra Large set both cover the top end of Class A weight and tire size; the Camco 44492, MaxxHaul 70472, and ROBLOCK options are reasonable for Class C and smaller Class A rigs once you’ve confirmed your actual per-axle weight. And if you’re towing a car behind the coach, don’t forget it needs its own, smaller chock too.
