ours sits in our gravel driveway a lot in the winter (although we can go camping almost anytime of year here in the Pacific NW), so I put 2x12's under the wheels to keep the tires from sitting on cold wet bumpy ground. Also put Harbor Freight covers over them (only about $20 for four, are canvas and work great). I elevate one side to level the TT cause sometimes we use the fridge to hold extra food around Thanksgiving and Xmas and as we live in a park model use it as an extra bedroom and bath for visitors.
