Rob,
I think your on the right path w/ the dealer and having them look at it after LD w/e. For all tense and purposes, camping season is winding down and scheduling a date to bring "her" in is a good idea. In doing so, they can see what the problem is, contact the mfr and if possible get fixed ASAP cuz I'm sure you want to get into storage by end of Oct. One fly in the ointment tho is if you have any trips planned between LD w/e and end of Oct. But by all means, get this addressed while it's still under warranty.
