I just wanted to add to my previous post:
When we picked up out trailer at the dealership in Tucson, I thought the coach sat a little nose-high (unhooked). Checked it with my torpedo level and confirmed that the trailer was okay side to side but nose high - the bubble was fully against the forward line on the level. I know - probably good enough.
I mentioned this to our assigned service rep and he told me that in order to adjust that they would have to dig into the belly, find the sensors, and make the needed adjustments. Probably take a couple of days to cycle us through their very busy shop.
I had read on here that someone had "reprogrammed" their leveling system.
So, rather than arguing with this guy, and the fact that we needed to be headed for home, we took the trailer anyway.
Got it home - printed out the manual-and re-zeroed level. The system now works as advertised.
Had it not been for the knowledge gained on this forum, I would have been at the mercy of this less-than-knowledgeable service rep. Thanks again to all on this forum who choose to participate and share their knowledge and experience.
