Jerry,
Keep in mind most of the folks who read the RV forums are looking for info (like you), have a problem and are looking for a solution or to complain, or like to provide advice (like me). So you will only see posts from a very small group of RV'ers. The majority of RV'ers don't look at these forums.
That being said any reviews you get maybe slewed depending on if the responders have or are having problems with their RV's matching the ones you are looking at.
If you have access to large RV Resorts and campgrounds it may make more sense to drive through the resorts to see what most folks have and talk to the RV'ers with the TTs you like.
