grege - It doesn't surprise me the air beds are different sizes (for the Jammer and the Roo, that is). That's good info, and I'd be concerned about the quality question, which we can't address here (i.e., whether the air bed is the same quality as the one in the Windjammer, just smaller). RockwoodNV's bigger dilemma, I imagine, is that there is very little comfy about a jacknife sofa, either as a couch or as a bed.
