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

We bought the ratings book from the RV Consumer Group when we were looking (www.rv.org) and chose the most highly rated models then went looking. It's not a perfect system but there is no Consumer Reports for RV's that I know of.
You can search this Forum for the models you narrow it down to but pay more attention to the problems of a particular make/model than how enamored the owners are with their rigs.
