Jim,
I just happen to have some info on the "Ultra Van" in my files.
These interesting small motorhomes were made by Ultra Inc. in Hutchinson, Kansas. They are completely self contained, have a low center of gravity, and are to be treated as pasenger cars as far as "driving one around."
THERE IS NO CHASSIS!! At first this may come as a shock, but when you
understand the construction, you see the logic. As in the design of an
airplane, boxcar or transport trailer the sidewall is relatively rigid.
So much so that a frame is useless. Since it is so flexible that a frame
bends slightly under its own weight, the sidewalls actually would have
to hold it straight. This would require that the sidewalls would have to
be built stronger to carry a frame if used.
We previously mentioned that we got equal strength with less than one-third the weight using aluminum versus steel. But the shape or design is what gives the shell or body added strength. The air frame engineer would refer to this as "monocoque" construction. This means it is a one piece unit with an ovate shape, patterned after the fuselage of an airplane. There are a series of stamped aluminum bulkheads going around inside the shell giving added strength. Remember the Douglas DC-3 and its durability?
There are many commercial adaptations for use of the Ultra Van. It can
be used as a Field office of a showroom or on construction projects. Many
salesmen find it ideal for traveling. It saves them time and money. Carrying
samples gives added impact, for such a unit is novel enough to
attract extra attention.
As far as we have been able to learn the ULTRA VAN has more horsepower per pound of weight than any other motorhome. You can cruise and take hills at your customary driving speed. You get light passenger car gas mileage, and it handles and rides like a car.
In considering buying an ULTRA VAN keep in mind that the first unit
was built as something to live in and enjoy. As new products became available
and new ideas presented themselves, improvements have been made. Practical
livability is always foremost, rather than just building
something to sell.

These are some of the lines from a little sales blurp that I have a photo copy of. There is no detailed info on the mechanics of the unit, or on the years manufactured.
In the town where I live there is an Ultra Van parked on the side of someone's driveway. It looks sad, forlorn and beat. I've wondered about stopping in and checking it out sometime in the future. All I need is another project!! That I don't want at this time. My next project will be my '47 Airstream, I hope!!
