Using rebar and conduit and a canvas tarp the span is 12 feet by about 10 feet that folds down to about cab height when transporting on a trailer.
Trying to make it simple so 1 person can set it up but has been hard.
Use a knuckle or a hinge on the truck end put ridge pole on throw tarp over use a hinged upside down v ridge pole support and add roof poles and guy supports as necessary
