Stabilizing jacks...and tire protection for 2+ year stay

I would let the tires sit on wood or a plastic pad to keep on the ground dirt or what ever. Our alpenlite sits on plywood both at home and during the winter in Az. I do this because I feel it is better and because I can. Keep the tires to max pressure. Sitting for 2 years isn't good for rv tires . The answer to this is ya gotta do what ya gotta do. be safe
