wnytaxman brings up some very good points. I know for a fact that Tiffin has had some major problems with cracks on the curve part where the roof meets the side walls on the longer Phaetons. That takes a major shop to repair and that is why they are all piled up at Red Bay.
Tiffin does manufacture a nice looking coach, but they do have major problems that need to be corrected.
But it is not different then when Monaco bought out Safari and they also had so many problems they almost went under because of all the recalls. That is why they built in 2001 the big shop in Wildwood Florida.
