I've also been looking at the 36TB, 37QB, and the Sanpiper 365saq I think it was. Just looking for a quad-bunk, outside kitchen, and extra 1/2 bath with 2nd outside door. The 37QB has the door on the side as well. Sounds like you have a long drive ahead but well worth it in the end. I agree they are hard to find, so if I see something local it might be worth jumping on.
can I ask what you are pulling it with?
