Best Way To Stop An RV From Creeping Downhill While Parked  

Updated 07/09/2026 | Published 06/25/2026

Question:

I have an RV parked on a slope. It is the hardpack surface of the desert. The entire site is sloped. I have leveling blocks under my front wheels. But over time I am slowly not level…. I am sliding down hill, very very slowly…after three weeks it is enough that I have to do something …. this seems to be happening with the wild wind storms New Mexico is plagued with. What do you have that I can place under the front wheel blocks to stop this?

Hey Kat, thanks for reaching out. Honestly, I don't think putting something under the leveling blocks is going to solve the problem. If the whole RV is slowly creeping downhill over the course of a few weeks, the issue is that the tires are gradually sliding on the hard-packed surface, especially with wind loading on the side of the coach. The leveling blocks are just along for the ride.

If it were me, I'd be looking at heavy-duty wheel chocks with a much more aggressive grip on the tires, not a different block under the tires. Something like the Super Grip Chock Wheel Stabilizers # UF21-001091(if it's a tandem axle) along with a heavy rubber wheel chocks like part # 337WC1085H with a textured base will do a much better job of resisting movement than plastic leveling blocks alone. If the site has enough slope that the RV is actually creeping downhill over time, I'd also try to reorient the camper or pick a flatter pad if possible, because that's more movement than I'd consider normal.

What kind of RV do you have?

Thank you for the reply. Unfortunately I cannot change sites. I knew this site came with challenges….but it is otherwise a truely awesome place at less than half the usual cost. So… I have a 21 Honeywell motor home. 1989. I don’t think the wheels are turning…I think everything is creeping down. I am starting to think it is walking in the high wind. What do you think of a concrete pad down on bare desert floor…then a leveling block? It there a better gripping leveling block? Maybe hard rubber open grate? Thank you again for your help!!!

@KatS Hey Kat. Thanks for the extra information. If the motorhome isn't actually rolling and is instead slowly "walking" downhill from the wind, I don't think a different plastic leveling block is going to make much of a difference. A concrete pad would give you a more stable surface, but it's still fairly smooth, so I'm not super confident it'll solve the problem by itself. If it were mine, I'd try putting a thick rubber stall mat or another heavy-duty rubber mat under the leveling blocks. That'll add a lot more grip between the blocks and the ground than hard-packed dirt or concrete alone. I'd also make sure you have good, heavy-duty wheel chocks on both sides of the tires. Unfortunately, I don't know of a leveling block that's significantly grippier than the standard plastic ones, so I think adding a high-friction rubber layer underneath gives you the best shot at stopping that slow creep. I hope that helps and let me know what ends up working. I'm curious to hear how things go.
