How to improve fuel economy with a tonneau cover

Snugtop, a company that makes tonneau covers and bedcaps for pickups, [...] conducted a very intensive test this month at Irwindale Raceway in Southern California. Using fullsize pickups from Dodge, Ford and Chevy, the trucks were driven 100 laps at 45 mph. Two had tonneau covers and the third had a bedcap. The gas tanks were topped off and the tonneaus and bedcap removed for another 100 laps at 45 mph. Bottom line: Snugtop reports a 1.3 mpg improvement and says even better mileage can be expected at higher speeds.
Full details of their methodology is available, which is nice. (Have to go to the manufacturer's site to read it.)
