Our previous coach, a 40' Tuscany, only had one problem, the screw hatch for the sewer outlet was off center from the dump outlet. Dealer cut a section out of the wet bay floor, rivited in a new piece of plastic and reinstalled the hatch, easy fix.
Our current coach has only had a couple of small items to fix. The biggest problem was intermittent loss of camera signal, turned out to be the switch box. After we had the coach one week the rear AC compressor wouldn't kick on. Went back to the dealer, freeze sensor was bad, not a Thor problem. The only Thor problem was a short in the step light from faulty wiring.
