[hypoxia]

I have had height control valves that would intermittently raise the front of the coach.  On my last coach I had several occasions to extend the generator and hide in that cavity while raising & lowering the coach alongside the road because of an intermittent HCV.  If you decide to work on the 6 pack, HERE is a thread showing the parts needed.  It's probably a good time to rebuild the whole thing especially if it doesn't stay level when camping in manual mode.

I can't see where the HCV being on the sway bar would be a factor.
