Fishsizzle - I think John is on point. You're knowledgeable, check temps etc. and you haven't flattened one side of your tires (as would have happened by the dealership assertion). IMO they are pulling one on you. $1500 to check some wiring??? Really??

I would take the info they gave you, grab the GM/owner and show him, have him grab the service manager and tell them we were "going to take a walk" - then go thru their little explanation. It sounds way bogus to me.

I've had my awning torn off, scrapes on the side of the trailer, bent steps, bent roof ladder, and any number of "things" happen while at the dealership that they "didn't know about". They were fixed, at times after some tenuous face offs, but they got done. I'm afraid you may be facing something like that. Good luck!
