Ahoy Roy:
Come to the Expo in detroit, Aug 11-12. You'll see all manner of sleeping situations folks have developed for their vans. Motels for the expediters, including van drivers, are a luxury nowadays. We generally get a room on sundays after doing van wash, clothes wash chores. During the remainder of the week we have plenty of room in our 72" x 48" sleeper, located behind the seats and separated from the freight by an air tight wall. Others we've seen have bed located in a raised roof and lowered electrically or manually. BTW the best way to get a run offer is to commit to a motel room during the week.
