I recently purchased the Camco Wheel Chock with Rope (Pack of 2) for my trailer, and I couldn’t be happier! These chocks are sturdy and durable, providing excellent stability to keep my trailer securely in place, even on uneven surfaces. The attached rope makes removal so easy—no more struggling to pull them out from under the tires! They’re lightweight yet strong, and the pack of two gives me peace of mind knowing both wheels are well secured. A simple, reliable product that every RV or trailer owner should have. Highly recommend!

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.
