The one you've shown is sub-optimal. The most it will do is fill the wake.

An effective aerocap will transition [gaplessly] off the cab on the top and sides to prevent the turbulence your example will induce.

How about this?



I talked to the manager at the pizza parlor and he knew it improved the gas mileage, but not by how much. An aerocap that tapers on the top but not the sides would have the same rear face. So it's midway between a cap and a half-tonneau.

The way it works is it sets up a rolling ball of air in the bed that causes air flow to skip over instead of invade the bed.

It would be improved by beveling the top corners. The low road to results might be to get a utility box and slide it from the front of the bed to the rear. Instant half-tonneau.

In fact you could A-B test the front and rear locations, and generate useful data for other pickemup owners.
