Well I have a TT, and I placed bubble levels at all the corners on the exterior using a contractor's level. I use these to level from side to side. Once unhooked, I level front to back with anoher bubble level and raise the front jack a little past level to allow for runoff and to keep my head above my feet in the front bedroom. No problems with the fridge or doors or the DW.
