Nuts. And here I thought I'd come up with a Great Idea (tm).

I've been noodling on this for a couple of weeks since I read the thesis from the guy at the Naval Post-Graduate School. There was a picture in there about research NASA did in the 80's (IIRC) on the optimal shape for a large truck/bus design.

A sloped bedcap + an inflatable boattail would be great for my monster F-350. When the weather improves, I plan to have another go at grille block mods, as the bed cap is a larger project and/or expense.
