We have a 2013 Challenger 37GT. We bought it as new last August at CW. We have had it at CW more than we've used it! Went in for warranty work November 14 and got it back January 4th. Put it in our storage. Went yesterday to show relatives and a trim piece on the outside of the bedroom slide out had fallen off. All the screws looked like they were sheared off. We found most of them but now we're looking at an appointment on Feb. 3 to get it fixed. We love the coach but we're stuck with CW for warranty work. Have not heard from Thor concierge other than a questionnaire which we sent back 2 weeks ago.
