Came away from the RV show in Allentown last month with many of the same observations; do not see any floorplans I like better than the one we have.  No way will we own a trailer with an outside door that opens right on the head (although I understand the logic behind the design).  Airstream or a Class B?  In my dreams. 
We've owned our current TT for nearly 14 years and I anticipate it will still be behind our TV for another 5.  DW and I would have to find something we REALLY like better before parting with our Coachmen.
