Really need advice

[xxclaro]

Thanks Frank. As for rounding the leading edges, I'm trying to figure out how best to do that or what materials to use. Should I cut the sharp edges back and try to find some sort of round edging material, or would it work to cover the edges with something round, say like a 3" plastic pipe cut in half?

It looks like you're towing a parachute. You should leave the weight on the tongue, along with the aero, and it might tow better.

My first thought is and Aero wing or wind deflector on the truck like one would find on a tractor trailer rig. Second add a rear aero effect to the back of the trailer with some simple barn door style hinges, 1/4 ply wood, and a few struts. Looks to the current OTR rigs for a little inspiration. As the trailer is short I'm not sure if side skirts would benefit too much.

There's a trailer down the road where all but the hitch itself has been used to make the pointed triangle at the front of the trailer. This is a design from the manufacturer. You might have enough room to put the nose on your trailer using the triangle up front.

except vee-noses aren't better aero unless they fill the gap better than a flat nose.
