QUOTE Tailgate up/down benefits depends on the bed length and cab size. I have had pop bottles blow out of the back of my Ranger with a 7' box, but I still have leaves from last fall swirling around in the back of my F-150 with a much larger cab in front of a 6.5' box. A pickup cab will create a nice swirling action that is kind of like a fastback on a car, it just swirls there and more air coming over the roof just glides off the back of the swirling air... problem is with a longbox the tailgate catches it wheras with a shorbox the tailgate takes part in the cyclonic action too.QUOTE
if you could harness all that air and run it into the intake you might get better mpg's
chop top, bed bob, just take the sawzall to it and cut off anything you dont need.
