Stove top! Years ago on these forums someone said to level the stove top... if that is level, everything else is fine. Really annoying to try and cook eggs that keep sliding to one side of the fry pan.
When we first got our TT, I leveled it in the driveway using a level on the stovetop and then put stick-on level indicators on the front and side corner of the outside of the TT. Someplace easy to see when pulling into the campsite. I recheck every year or so, but so far so good!
If the stove top is level but the refrig is too far out of level to run correctly, then something else is really wrong with your camper!
