DW has a co-worker who has a Freedom Express. They had some serious issues to deal with from new, in particular the slide. Don't know any details.
We used to have Catalina. We're now on our 3rd TT (different brand). Looking back on it, the Catalina actually was decent quality in comparison and as far as TTs go in general. Not a big plus exactly, but the Catalina had cabinets assembled using pocket screw instead of staples like most use. The base cabinets and counter top were rather wonky tho.
Discerning "quality" between brands and models isn't really possible IMO. All TTs have the same brands of components like Suburban, Dometic, Atwood, Lippert, etc. and it boils down to mostly to workmanship. Wiring for ex., can we well done one day on the assembly line and poorly the next. Our current TT is the identical model to the previous one and the previous one was put together better. Go figure...
