Effect of a traditional pickup camper shell topper on drag / mileage

To add to the discussion:

1) http://ecomodder.com/forum/showthrea...p-off-601.html

Relatively well done on-road testing shows that specific cap increased drag.

2) http://ecomodder.com/forum/showthrea...ruck-1228.html



Obviously "traditional" cap styles vary a lot. Some increase frontal area, and have insufficient radii on the leading edges. Others are truck-specific and are nicely integrated into the OEM shape at the back of the cab.
