In spite of your preference, I have been using a single bed camping air
mattress from Wal-Mart for years. I put it on top of my Jeep Grand
Cherokee
and fill with gravity. Need a water bed filling kit to attach hose to the
receptacle. Roll it up when done and it's out of the way. Holds 40 gallons
easily---enough for my '27B


I'm rapidly coming around to your solution. My guess is that you are using
the 'Coleman's Kid's Air Mattress' ($12 @ Wall-Mart) that is 28" x 59"x 6"
which will hold about 40 gallons and neatly fits on the roof of the Grand
Cherokee.

However, somewhat belatedly, I just did the W&B on the Nimbus 2C with regard
to water ballast. At the 1433 pound MTOW I will need 500 pounds of ballast
or 60 gallons. The CG moves slightly forward from the current 80% aft
position. (Now I know why the POH specifies 51 PSI in the main tire.)

So, the Kids Mattress isn't going to do it with one trip to the water hole.
Anybody know of a slightly larger waterbed/air mattress?
