Newbie fed up with so much misinformation on set up of a TT

Many times we have set up on ground with a slope. In this situation it may take several inches added to one side or the other to level trailer side to side. We use one or even two boards under both tires on the down side. Front to back level with hitch jack. Once we get close to level we will tweek it with the stabilizers. When on a concrete pad this won't be needed. We like remote campsites so it is almost never level to start.
