Does anyone have any idea of what kind of forces a 6 foot wide, 3 foot long wing would see angled up into the wind at say a 45 degree angle or more at say up to 70 mpH?
I was thinking of making the frame out of conduit and maybe trying foam covered in fiberglass. Like a surfboard with conduit just under the skin all aroundbthe edge. Then hinged at the front with drop down adjustable legs to get the angle if towing, or taper if unloaded

*no data has been published for a non-towing truck with up-swept wing.
*there hundreds of different airfoil shapes which have been tested,@ zero-lift,to maximum lift angles-of-attack.Abbott and Von Doenhoff's book would be the source for that data.
*a simple inclined surface at a fixed angle on the ground or on a wall has been tested but I don't have that with me.Sighard Hoerners book,Aerodynamic Drag, would have that.
*If you're running without pulling a trailer,the wing should be slanted downwards.Here are some examples of what a rear slope can do
