1989 E-150 4.9L C6 with 3.08:1 gears and 28.8" car tires. Has a ~4" tall fiberglass cap on the roof (pop-up camper top). Has had NO efficiency mods of any kind, just maintenance to get it road-worthy. I drove a Ranger 2.3 for a few years with a ScanGauge II and was getting 20% over EPA ratings consistently. DWL yielded the most improvement over my other hypermiling strategies. Truck was an automatic so P&G was out (for me anyway, I know some still do it) and ran heavier than necessary tires (for durability off-road and on crappy dirt roads).

Planning a big tune-up and a couple engine mods right now and doing aero research.
