It sounds as though you may have bought at one dealer to save $$ & attempting warranty work at another. Unfortunately RVs are not automobiles, the non selling rv dealer is in no way obligated to do any warranty work on any rv they did not sell. You may find one willing to work with you but expect to be constantly put at the end of the line behind those they sold & most likely not going to go to bat for you with the manufacturer as strongly as your selling dealer.
If however you are using the dealer you bought from & they are charging you out of pocket you need to be in contact with the manufacturer area representative as this should not be happening, you shouldn't have to pay for warranty work at your selling dealer.
Unfortunately there is no one from RW reading/monitoring this forum, see disclaimer at the bottom of the page.
I do not work for nor receive any compensation from RW, but due the fact you got one with issues doesn't mean all are crap. You may have gotten that 1 in 100 built with issues, but sounds to me like you got a dealer that SUX!
