Jim,

The thing I would be worried about is blowing an air bag while trying to level on very sloping ground. I only say this because my Thomas aux compressor, capable of 150 psi when the HWH system bypasses the pressure switch, blew out one of my tag bags while I left it in autolevel.

Good point, will watch it when leveling with engine running. My aux comp is set at 90 psi, so should be okay there.
I normally shut hwh off after first leveling, is there a reason I should leave it in autolevel?
