Homebuilt Streamlined Camper Car, 1941

I picked up a stack of 1940s Popular Science mags at an estate sale this weekend and found this crazy homebuilt car pictured in the letters section of the August 1941 issue.

The builder sent in a photo of his car with a note, explaining: "An article you published about a year ago, on a combined automobile and trailer, gave me an idea. The photograph shows the result, built in spare time over half a year at a cost of $250.  A frame of welded metal tubing over a Ford V8 chassis is covered with sheet metal. Over the engine is a metal framework supporting a table. Where the dashboard was originally, is a place for a stove. Covers over the front wheels make seats for the table.  Back of the driver's seat there is room to install two bunks as in a trailer. Running boards are inclosed and are at the level of the bottom of the body.Windows slide as on a station wagon, and there are doors for oil filler, oil gauge and gasoline pipe filler.  Building the framework over the wheels gives extra room and eliminates fenders.  - M. C. P. Downey, Calif."

This thing is rad, and looks like a bizarro homebrew Multipla.  Now I need to find the article that inspired it!  I'd love to know what happened to this car, and if M. C. P. built any other innovative vehicles - anyone that could build a car like this in six months had to have other stuff up his sleeve.
