I think if you do some reading here you will find your timeline for repairs is actually pretty good. Consider that even before the RV sale boom it was very difficult to get in to a dealer repair for warranty work. If you think you will get the same quick service with a RV that you get if you take your new car to the dealer you are going to be very disappointed.
So the previous suggestion is good. If there is nothing other than the hanging wire, try the unit again once you are loaded and if comfortable, make your rip. I promise you you will have more warranty repairs on the list when you get back.
