I know it sounds like an ad for tonneau covers but it is a study done in wind tunnels of several different covers on Ram, Ford and Chevy pickup trucks.

It is an interesting read.
Thanks for sharing, interesting. I read another study quite a while ago that actually drove the trucks over the same section of road within a very close time span, with and without tonneau covers. While they did not measure the coefficient of drag, there mpg drop conclusions were very similar to what this study extrapolated. While interesting, I still conclude, the slight gain in MPG is not significant enough to make a buying decision, solely on potential mpg gains.
