Do you have your jacks up or down when the coach is in storage? I store my Class A in the back of an RV park in Texas. Due to the weather, we will probably have it out at least once a month. So I am not talking long term storage. The ground where it is parked seems to have an asphalt base covered by crushed stone. I have only had the motorhome a month and so far have not used jacks. Either way, should I be parking the tires on some type of board or plastic? I put covers on the tires if they are going to be sitting more than 5 days. Thanks. I can tell you how valuable this forum is for someone who is new to a motorhome. You guys/gals are great!!
