I found B190.com the other day and requested a login account, Skater!
Storage issues aside, like Skater, I think you'd do well to use the time to search for just the one you really want, and then once you find it, spend the time wisely before your "big trip" using it and bringing it up to snuff. There's nothing like starting out on the "big trip" in a moho that you have no experience with and no confidence in!
I had seen photos of the wet bath model... but didn't know when that change came about. There's also a difference in living space floorplan in those coaches; the stove and refrigerator swapped sides IIRC.
