Great rv wheel chocks
Style: w/ Rope Design, Size: Pack of 2
After ten years, I finally decided to replace one pair of these. They have taken abuse through eleven camping seasons with my rv and I gave them to the new owner when selling my old trailer. I like these because I can use my orange plastic deadblow hammer to get them tight to the wheels. They are pointy so they really get under the tire and stay put. The rope handle makes them easy to pick up and move to the storage bay.

Excellent leveling blocks for our (heavy) Sprinter van
Size: 10.5' x 10.5", Color: Gray, Size: 10.5' x 10.5", Color: Gray
This review is for the FasTen XL 10 pack (10.5" × 10.5", 10 ea.).
We have a 2024 AWD Sprinter van that's been fully converted to a Class B camper. Fully loaded, the van weighs ~ 8,650 lbs, and sits on 265-mm-wide (10.4-inches wide) BF Goodrich AT KO2 tires. The width of the tires were a driving factor in deciding to purchase the XL-sized blocks instead of the standard blocks. In addition, each wheel carries more than a ton of weight, especially in the rear. To be honest, I had my doubts about how well these plastic blocks would stand up to such loads.
I am happy to report that after three weeks of daily use on both dirt and paved surfaces, these blocks have performed very well, showing no signs of cracking or deforming. While in use, the blocks sometimes appear to be bent (and possibly they are, but this could also be an illusion). Nonetheless, when stowing them, the blocks are perfectly flat and stack nicely for easy storage in the van's equipment box. Just knock off the dirt and pebbles, stack them up using the convenient handle, and you're ready to go.
