porthole, I wonder if it's possible that the computer in the leveling system is not taking enough load off the wheels? Have you tried after hitting auto level mechanically raising the front and rear a bit?
I place one of the levels (see pic below) above the controls and one on the side of the propane box, so I have a mechanical way to re level or temp level as shown in pic above when staying hitched. I am picky so I used my Laser Level and got all 4 corners of the bottom of the frame the same dimension above the Laser Line. Then go thru the procedure to re set "LEVEL". Then I used Permatex Black Gasket Maker to attach using tape to hold them in place while adhesive cured.
I did remove the stick on tape.
So by doing this you could manually hit extend front a bit then back extend until it's level again.
