Many people buy units from the show. At the RVIA show in Pomona this year, we were there the last weekend and there were dozens of units with sold signs on them.
However, check every inch of the unit BEFORE taking possession, including the roof. It was raining when we were there (yes, actually rained here in SoCal one day
) and kids were climbing all over the units, some were a mess. Also, check the hours on the generator if it comes with one. When it's hot, they sometimes run them if there isn't power to that unit.
There is a discussion on the Tiffin forum here where someone purchased at this show and when they got it home, found a hole in the roof with a crappy repair. Looks like damage at the dealer but the dealer never disclosed it. Plus, there were over 200 hrs on the generator. It was still sold as new because it was never registered to anyone else. Here's the link if you're interested.....it's a long read:
