It looks like a great product, and I hope they become the norm.

For <1/10th that cost the same thing or better could be made of 1/2- 3/4" Coroplast. This cost would include side skirts and radiused leading edges of the trailer box, not to mention an air dam for the tractor, and pizza pans from WalMart for wheel covers. Then, the whole rig would probably be closer to ~15% fuel savings.
1/2" Coroplast or larger has large enough hollow flutes to insert battens for stiffening. Dowel rods would work, or aluminum tubes, etc..
