just curious if anyone has actually noticed better mileage on both freeway and surface roads, when your tailgate is down or you're using a bed extender?
Damn I had no idea...no.watch mythbusters much? guess not...

Tailgate Up vs. Tailgate Down
This was revisited in More Myths Revisited.
Myth statement Status Notes
It is more fuel efficient to drive a pick-up truck with its tailgate down, rather than up. Busted Driving with the tailgate down actually increased drag on the pick-up and caused it to consume fuel faster than the identical truck driven with the tailgate up. It was later revealed that the closed tailgate creates a locked vortex flow that created a smoother flow of air over the truck. With the tailgate down, the trapped vortex was dissipated and the drag increased.
