As promised, I have revised the Midget drawing on my site into the
Midget 2.
This has an all-steel chassis and I've stolen Bob Kloppe's idea of replacing the fixed bed with an extending settee. This leaves space for a porta-pottie if wanted. All the geometry of the profile is shown.
One thing that turned up in this redesign is that, according to my estimate, the original Midget should be very light on hitch weight - I've moved the axle 4" rearward to allow some weight to be carried in the galley. I guess anyone who thinks of building this should speak to Bob Kloppe and find out how his turned out for balance.
