I have to ask, why are you returning it to them again, when they were unable to repair it properly the first time? Why are YOU driving it there? Are they paying your expenses?
I read all the time about THOR returning rigs to Indiana, as sort of a
PR opportunity, combined with the fact that most of their dealers are either inept, or unwilling to make repairs, or both. The success rate on Indiana repairs seems to be around 50%.
My success rate at THOR authorized repair facilities is ZERO. I don't blame the repair facilities for shoddy THOR construction. I also understand they have to "negotiate" with THOR endlessly for warranty repair authorization, and approvals. Now they want me to return it, under warranty, at MY expense, to Indiana, because the local dealer has given up on fixing the slide. And the slide is only the beginning of the problems.
Run as fast, and as far as you can from THOR. They don't care about their customers, or their reputation. Their "warranty" isnt worth the paper its written on!
