This is similar to an episode of Mythbusters years ago where they tested the theory of a trucks tailgate being down increased mileage. The myth was busted as the truck with the tailgate up had much better mpg.
I can't find the video on the net but I remember them doing test in wind tunnels and it clearly showed the difference.
Somewhat off topic but still interesting.
Interestingly, the best mileage I've ever seen in my D'max was on a trip to CO several years ago, with a 14 cu ft chest freezer in the back, right up against the cab. I saw 23+ mpg while running 75 after DW told me that my fuel-saving 65 was too slow. :-) Surprised hell out of me, that's for sure. Simply =has= to be aerodynamics.
