We have a full-sized futon on our double bed in the 63 Overlander. It fits snugly and bends up the wall to make a nice back support. Eventually we will mak a slide-out bottom so the bed can accomodate the entire futon. Pictures of it are on my blog (which I haven't updated all winter...ugh!) -Tracey www.geezitron.com/1963_airstream
