We had a totally opposite experience with Thor and warranty work. Purchased our ACE from Camping World in Madison. In the first year we owned it they had it for over 5 months for warranty work. Didn't get it back until it was out of warranty and things were not fixed and they actually lied about repairs that they never made. Told us that Thor had denied some warranty items also. When we contacted Thor on picking the unit up they authorized us to take it anywhere we wanted and have them contact Thor. Upon going over all the work orders from Camping World and talking with the Thor rep we found items that we were told were denied by Thor that had never been submitted to Thor. We also found repairs that weren't done but Thor was told they were completed. Thor covered all of our repairs and the local dealer said they were very pleasant to work with. So I'm curious scrubjaynest, have you actually been talking with Thor or are you receiving this information from the dealer? If it's the dealer telling you Thor won't stand behind it, I would suggest you contact Thor directly. We found them very helpful.
