In case any one is interested:
That Tow Vehicle looks to be a Tatra 87, a Czech car. Quite
a unique vehicle, @ 3000lbs, with an air-cooled V8. http://en.wikipedia.org/wiki/Tatra_87
The trailer is a Bowlus - the original aircraft style constructed TT, the
actual forerunner of the Airstream. They were very expensive for the times
and went bankrupt. Wally Byam, the founder of Airstream, had
worked for/with them and bought the assets at the bankruptcy sale
and also hired some of the workers... . The trailer is probably a Road
Chief model @ 6ft x 18ft and @ 1100lbs. They used small steel tubing
for the body framing.http://www.openthinkinc.com/bowlus/index.html
From what I've read on the topic, and for our purposes - as amateur builders -
matching the frontal size of the trailer to the max cross-section of the tow
vehicle and doing somewhat of a kamm-back effect on the rear of the trailer
would seem to be the most beneficial, or the most result for the effort.
If you have a house - you have a hobby.
