Getting an RV level at a campsite is easier when the equipment matches the tire arrangement and the amount of height adjustment needed. Camco makes stacking blocks, drive-on leveling ramps and ramp-and-chock sets. They are not interchangeable: some are flat platforms, others raise a tire along a curve, and caps are accessories rather than complete levelers.
Three ways to level a parked RV
Interlocking flat blocksBuild an appropriate stepped platform beneath tires or supported leveling points. Choose a sufficient number of blocks and follow the manufacturer's maximum permitted stack height.
Drive-on tire rampsUse a shaped incline to adjust a tire's height. The Camco 44535, 44573 and 44425 have different height ranges and contents.
Caps and chocksCaps finish compatible block stacks. Parking chocks help restrain a stopped trailer; a leveling ramp does not automatically replace a correctly positioned chock.

The block dimensions describe individual pieces, not a guaranteed tire-platform footprint at every stacking arrangement. The lift figures apply to the specified ramps, not to flat blocks or caps.
FasTen stacking limit: Camco specifies a maximum recommended stack height of 4½ inches for its FasTen interlocking leveling blocks. Do not exceed the manufacturer's instructions even if additional blocks are available. Always use stable ground and confirm that the support surface is suitable for the vehicle.
Before driving onto leveling equipment
- Park on firm, suitable ground and check the vehicle's tire loading, axle spacing and manufacturer's leveling guidance.
- Choose tire-sized blocks or a ramp with enough clearance around the wheel well, undercarriage and neighbouring tire.
- Keep drive-on pieces aligned and interlocked as intended. Do not improvise a tall stack with loose or mismatched parts.
- Use the matching chocks where the product calls for them, as well as appropriate independent wheel chocks and parking procedures.
- Use approved lifting equipment and supports for servicing a wheel. Leveling ramps are not vehicle-repair jack stands.
Questions about Camco leveling parts
What is the difference between 44505 and 44512? Both contain ten blocks, but 44512 is the larger-footprint FasTen model with an integrated T-handle for carrying and storage.
Does 44535 include wheel chocks? The kit contains two curved leveling ramps. The separate 44425 kit includes two matching chocks as well as its two curved levelers.
Can I use 44500 caps instead of a leveling-block set? No. They are top-cap accessories for a compatible existing stack.

To find independent trailer wheel chocks, see our Camco wheel-chock comparison. If you have a tandem axle and need between-tire stabilization, consult the BAL wheel chock and tire leveler reference. Neither type should be confused with a load-bearing leveling block.
