Block-style wheel chocks and X-chocks solve two different problems, and most camper owners actually need both rather than one or the other. A block chock keeps the trailer from rolling; an X-chock wedges between the two wheels of a tandem axle and noticeably reduces the side-to-side rocking you feel walking around inside a parked trailer (Parked in Paradise, retrieved 2026-08-08).
This guide covers the wheel chocks worth buying for a camper or travel trailer, the difference between block-style and X-chock designs, which tandem-axle setups actually benefit from an X-chock, and how to size a chock correctly for your trailer’s tire diameter.
Key Takeaways
- Block-style chocks should be large, durable, and heavy enough to genuinely resist rolling — that’s the core requirement for RV use specifically.
- X-chocks wedge between the two wheels on a tandem axle, both preventing rolling and noticeably reducing the trailer’s side-to-side rock while you’re inside.
- Camco is a common budget-friendly, easy-to-install pick; MaxxHaul’s heavy duty line is aimed at larger campers needing more robust chocks.
- Fastway’s ONEstep model is specifically built to stop tandem-axle vehicles, including travel trailers and fifth wheels.
- Solid rubber chocks like MaxxHaul’s 2-pack are chosen for traction and stability over hollow plastic designs.
The Wheel Chocks Worth Buying
Camco Wheel Chock
Camco’s chock is an easy-to-install, affordable block-style option, a common starting point for owners who just need reliable roll prevention without paying for extra features (Camp Addict, retrieved 2026-08-08).
Best for: budget-conscious owners of smaller trailers who want a straightforward block chock.
MaxxHaul Heavy Duty Chocks
MaxxHaul’s heavy duty line is specifically recommended for larger campers, where a lighter chock designed for a smaller trailer may not hold as confidently (Camp Addict, retrieved 2026-08-08).
Best for: larger fifth wheels and heavier travel trailers where chock size and mass matter more.
MaxxHaul Solid Rubber Wheel Chock 2-Pack
This solid rubber 2-pack is chosen specifically for traction and stability, since solid construction resists compressing or sliding under load better than a hollow or lighter-duty design (Camp Addict, retrieved 2026-08-08).
Best for: owners who want maximum grip and don’t mind the added weight of solid rubber over hollow plastic.
Fastway ONEstep
Fastway’s ONEstep model is purpose-built to stop tandem-axle vehicles specifically, including travel trailers and fifth wheels, rather than being a general single-axle chock adapted for the job (Camp Addict, retrieved 2026-08-08).
Best for: tandem-axle trailer owners who want a chock engineered specifically for that wheel configuration.
Block Chocks vs. X-Chocks: Do You Need Both?
A standard block chock does one job: it sits against a wheel and prevents rolling on a grade or uneven pad. An X-chock does that same job differently on a tandem axle, wedging into the gap between the front and rear wheels on one side, which locks both wheels against each other rather than against the ground alone — and that wedging action is what noticeably reduces the trailer’s side-to-side sway while you’re moving around inside (Parked in Paradise, retrieved 2026-08-08).
Single-axle trailers only have the option of a block chock, since there’s no second wheel on the same side to wedge against. Tandem-axle owners get real additional stability benefit from adding an X-chock alongside standard block chocks at the tires, rather than treating the two as interchangeable options.
Sizing a Chock to Your Trailer’s Tire
Match the chock’s rated tire diameter range to your trailer’s actual tire size before buying, since a chock sized for a smaller wheel can slip loose under a larger, heavier tire, and an oversized chock may not seat correctly against a smaller tire’s contact patch. Check the manufacturer’s stated tire diameter range against your trailer’s tire spec sheet rather than estimating by eye.
If you’re stabilizing the trailer for level parking as well as wheel rolling, our electric trailer jack guide covers the tongue-height side of the leveling equation that pairs with wheel chocking for a fully stabilized setup, and our low profile air bag jack guide covers a lifting option relevant if you’re leveling on uneven ground beyond what chocks alone can correct.
Frequently Asked Questions
Do I need both block chocks and an X-chock?
If you have a tandem-axle trailer, yes — block chocks prevent rolling while an X-chock additionally reduces side-to-side rocking. Single-axle trailers can only use block chocks since there’s no second wheel to wedge against.
What size wheel chock do I need?
Match the chock’s rated tire diameter range to your trailer’s actual tire size. A chock sized for the wrong wheel diameter can slip loose or fail to seat correctly.
Are rubber wheel chocks better than plastic?
Solid rubber chocks generally offer better traction and stability than hollow or lighter plastic designs, which is why models like MaxxHaul’s solid rubber 2-pack are specifically chosen for that grip.
The Bottom Line
Start with block-style chocks sized to your trailer’s tire diameter — Camco for budget simplicity, MaxxHaul’s heavy duty line for larger campers. If you have a tandem-axle trailer, add an X-chock like the Fastway ONEstep for the side-to-side stability a block chock alone can’t provide. Neither type substitutes for the other on a tandem axle; they solve related but distinct problems.
