Outdoors RV also has a decent 4-seasons package. They are owned by Nash /Northwood. One really good feature about Nash and Outdoors RV is that they both have heavy duty off-road frames. Frames on TTs can be problematic sometimes.
In the last year or two, TT manufacturers have been coming out with arched ceilings. Our arched ceiling is 6'-10" in the center and 6'-6" at the sides. You won't find really good deals on a TT that is only a year old tho.
Do they ever install taller entry doors as a standard feature? Ours is 5'-9" (actual clearance). Have never thought about what tall people do. Dexter Door makes them up to 80".
Dexter DoorOne thing we like about TTs is that everything is on one level.
