Here goes. My tt is stored at a ocean campground. Sandy soil. I do not have a vehicle to tow or move it with. I have 3 slides. A large living area slide and 2 bunk house slides. The bunk house slides are across from each other. Thus, I have 2 slides on one side. When the campground pulls the tt to the site, and sits it. The sites are pretty level but not great. I do as the owners manual says and level as best I can, put the stabilizers down and extend the slides. Sometimes I am ok, other times not. Front to back leveling is no problem, side to side , however is. In order to level side to side I need to raise the tires and place wood, or leveling blocks under the tires. How can I accomplish that? I saw a 12 ton round cylinder jack, that should lift it. Where would I place the Jack? On, the frame, or on the axle? I believe the owners manual says something about the axle for changing a tire. If it is unlevel, it makes sleeping in the bunks difficult. Any help reciappagreatly appreciated.
