The base chassis is an 8 1/2 foot trailer.
The plywood sections are so designed that you can use every bit of eight 4 x 8 ft. sheets of plywood - no waste.
You will need a trailer chassis to start however.
Trailer tires should be 4.80/4.00 x 8 inch, which are rated to carry 1200 pound loads at 60 mph.
Tent canvas should be 10 oz.
Use electrician's thinwall conduit for tent poles and ribbing.
Five pages ( 3 sheets - front on first sheet, front and back other two sheets )
B & W photos, illustrations, expanded views, materials list and instructional narrative.
My plans are from original source materials such as books, magazines and other publications and the pages are carefully removed.
