One of the best things about the Stepwagon is that the back seats fold down to make a really flat bed. Any Stepwagon up to 2005 with a "Butterfly Seat" can do this. Our own van has a full Honda curtain set, and we've added a double size futon, to make it a wonderfully comfortable home away from home on countless weekend trips to the mountains and beach. A double sized airbed would work just as well.
