Review on Red RV Leveling Pads - Valterra A10-0918 Stackers: Pack of 10, Multi-Use by Patrick Arnautov

They flex surprisingly little under the weight of a three-horse trailer in summer. I'm not sure about the weight of the tongue, but it pulls the truck hitch down 4-5 inches. A little pricey for what appears to be only a few ounces of plastic, but if they're strong enough to be brittle in winter, they're worth the price. If not, I'll give a few stars. Wheel chocks of the same brand are no less good: they look strong, excellent functionality, very low weight.
