I like the T40F with the full wall slide and rear bath configuration. I think that would be a winner in a 45' tag axle, but I still really like the sleek curved cabinets in the Constellation and the murphy bed/dual purpose space. It looks like Gulfstream doesn't really do quad slides or full wall slides plus two.

Rig: Don't own anything yet, but seriously considering 09 Tourmaster Constellation vs. 07 Newmar Essex, Tiffin Zephyr, or Travel Supreme Select... leaning toward TM Constellation.
