New prospective TT owner - how to pick a high quality model?

OK, so then how do I figure out who are the higher quality builders vs. the more volume-oriented builders? As an example, we rented a Holiday Rambler motorhome, which was OK, but the cabinets were cheap particle board, the carpet was low quality and it generally didn't have the fit/finish that we wanted. Then, we saw a Tiffin motorhome at a show and were blown away by the overall build quality.

So who are the Tiffin-like builders of the TT world?
