That's Dean Tennis' original tear. The Chummy II, built to replace it after some booger-brained streetracing Bubba in far west Texas turned it into matchsticks one bright morning and put Mr. Tennis in the hospital -- incidentally totalling his car -- is a thing of beauty, a bit like a cross between a sail-driven Corsair and a Conestoga. I'm given to understand that the original weighed well under 500 pounds, loaded, and was possessed of copious quantities of aircraft-style fabric-and-dope construction (roof, door, possibly more).
The trailer in the photo at
http://groups.msn.com/AeroFliteTrailers/vaillakeresortrally.msnw -- still can't link to fracking MSN albums, drat it -- is advertised as an Aero Flite -- although not, apparently, the Falcon model the company built from 1947 to 1949 in Van Nuys, CA. Perhaps it is a Hawk, although that is described as an 18-footer elsewhere; perhaps it is an early Byum/Airstream or prototype. It might also be an early Bowlus; the photos, while delectable for their detail of the windows, interior trim and taillights, are singularly uninformative with regard to any makers' mark or builders' tag the item might possess.
However, there is a 2nd trailer in that album, clearly an Airstream type, inside which are some pristine white and turquoise blue appliances.
