These post are educational at least they should be. It is a fact that during the manufacturers warranty period ALL warranty issues are done by the manufacturer Via a dealer or otherwise. It is also a fact that better results are achieved by dealing directly with the manufacturer as they have more influence with your dealer than we do. We call the manufacturer first then they clear the way to the dealer.
After the manufacturers warranty period many of the vendor items have a longer warranty period and we should deal with them direct. In fact I have dealt with the vendor direct during the manufacturers warranty period with better and quicker results.
These are RV's and a entirely different world than our trucks and cars in terms or warranty issues.
