Wow that's pretty great! Perhaps the easiest way to make a properly shaped aero-bed cover! Did you by chance measure the individual pipe lengths? Could almost make it into a DIY kit or at least set of instructions.

The kick-stand prop idea is nice and simple.
Probably a brace across the top somewhere near the middle of the bed, lengthwise, would really help rigidity.

The only thing I wonder about is the excessive side taper towards the rear. Why not keep it closer to the width of the truck bed? If you visualize airflow over the top of the cab, its coming over at full truck width. Yeah, some gains could be had by letting the air along the sides of the truck taper back in... but I just wonder if it would be more effective being wider at the very rear still. Hard to say.
