Hello, this may have no bearing on your situation, but we recently bought a Thor Hurricane. It came with 2 air mattresses, one was simply in a box inside the coach, a Coleman I think...it was for the electric drop down bed in the cab. The second air mattress, I looked all over for....to my surprise, it was actually stowed inside the fold out couch....you could not see it until you put the couch out all the way into a bed, and there is was, stowed neatly in a zipper bag that is actually attached to the couch bed ....
