I live in Canada where the temperatures get well below 0 degrees F at times during the winter. My motorhome is stored outside in the snow. My question is, “Is it okay to use the leveling jack system to level the unit and even to raise the RV off the ground to take some or all of the weight off the tires for extended periods of time in such extreme weather conditions?” — Brian
As a rule, you probably shouldn’t lift the coach off the ground. I would drive it up onto pads to protect the tires, and then cover them to protect them from UV degradation. There are many commercial RV pads available or you can make your own using acrylic cutting boards. Either way will keep your tires off the dirt.
In my opinion, the potential damage to the hydraulics is greater than the harm to the tires. Plus, and this is based on my own experience, the jacks can freeze to the ground, or freeze to the pads which freeze to the ground, so if you need to move the coach for some reason you won’t be able to get the jacks retracted. So, as long as the tires aren’t in contact with the ground, and they’re covered, they should be fine. —Chris
