While we're on the topic, I recently had the opportunity to sleep on an
Aerobed:

I must say, a very high quality and comfortable air mattress, and the
inflation pump is fast!.
Unfortunately the twin size is longer than the width of my Vanagon and the
mattress is not cuttable. I'm going to ask them for a price on a custom
size.
Disadvantage with air mattresses: COLD!
