Review on 🔒 Heavy Duty Wheel Chocks Set with Lightweight Carry Bag - Enhanced Grip Bottom, Rope Handle, and Travel Trailer, RV, Car, Truck, Camper, ATV, Garage Parking Compatibility - Reliable Warranty by Dave Hess

Of course we tested them on our first trip. We had to park our 5,000 pound trailer on a slope that dropped into a ravine. We put anti-roll bars and a wedge under both wheels on one side (there were leveling blocks under the other side) and didn't roll downhill. I like the carry case as the pads get dirty. It's nice to have a bag to collect all the dirt and keep the rest of the safe clean.
