My husband I were both in the fire service for 22 years. We learned a LOT about safety, for ourselves and for our rigs. Airstream gave us a plastic wheel chock, a little red one for our 2020 FC 23fb. Truth be told, that little red one is anemic for an expensive investment like this. We decided to go the route of our fire service roots, and get real wheel chocks, made of aluminum. Our LC the Rivet Ritz now will be held in place should she be in a spot that has any kind of pitch. We like the Zico brand, and found these on eBay. Here is a link if any of you would be interested in beefing up your chock blocks.
