Review on 🚌 XPORTION X-Shaped Wheel Stabilizer: Enhance RV Safety with Camper Wheel Chocks, 2 Sets of Stabilizers, Rust-Proof Tire Chocks & Built-in Wrench (3“-10”) by Mark Sharma

I plan to use these campgrounds but wanted to test them in the field before heading out into the wild. I parked my flatbed trailer on a hill, inserted a strut between each wheel set and removed the rest of the chocks. The trailer didn't move (it rolled down the hill in the past, whoops!), so I'd say they did their job.
