I'm thru taking the fiver out for the winter. Probably won't go out again for 5 months at least. Do you raise your rv so the weight is off the tires? I never have in the past, but at the price of tir...
Our fiver is parked at our home on a packed gravel driveway. We take it out once a month and it has a Big Foot leveling system. I have always kept it leveled with the weight off the suspension (tires not necessarily off the ground) since owning it nearly 6 years. I feel its better for the springs and tires. So for the extended period you are looking at, I say "yes".
