I have to say that is a sharp idea and very innovative. What is really cool is that you have no doubt a truely "stand-up" sleeper I am sure. What you've done with that expeditor van/Cube/box truck is interesting though, very similar to what some household moving companies have begun to do more & more in the past couple years. They're (household movers) are getting large straight trucks with attics over the cab, but incorperating a sleeper into the cargo box. You're able to identify these trucks by a window and/or vent on the cargo box just behind the cab. There's a small boot/crawl-thru space into the sleeper, which usually is very small though. The real neat thing about your cube van is that the sleeper is totally un-noticed, atleast by the photo's we see. Thats clever. As far as anybody can tell it's just a regular cube van like you'd get at a rental place, but it's not-it's much much more. Essentially you've built a sleeper un-noticed which to a degree safe guards your truck-'cause nobody knows you have all that in there. A very good job & very nice as well. Bob.
