Going to RV show- what to specifically look for in a TT?

I look at RV shows as a place to compare lots of floorplans and brands back to back to back. There will be 1-2 of each higher volume brands, which means not all 15 floorplans of each brand. So you'll have to narrow down your floorplan as well as brand, but do not expect your preferred brand to have your preferred floorplan/model at the show.
