Tiffin's are pretty much the best in quality and build from what I have seen and read, neighbors that have them, ect. We have been keeping an eye out for a 36-40 Tiffin pusher to tow our enclosed 24' for about 8 months and the good ones go within a few days. You might open your search to a short Class A. We had a 1996 30' Coachman (poor quality IMHO) with the F53 Ford chassis and 460 and it did great towing 8k lbs. The older class A's with NO slides generally have quite a bit more tow capacity since no added slide weight. Good luck with your search.
