I posted this on another forum, but figured asking here would be a bit more entertaining. I know myself the benefits of a tonnaeu keeping stuff dry, covered, etc. But here's my reason for posting:
Was talking with my coworker, whos going to be buying a truck in a month or two if all goes as planned. He has everything all planned and what not. And the talk of tonnaeus and bed covers came up. His one buddy, claims that having no bed cover is more beneficial then having one. Due to the air hitting the tailgate/inside of the bed, and projecting twords the back of the cab will help to "push" the truck along; Netting better mpgs. Which he has claimed he tested this.
While i can see his point somewhat valid, i still tried not to die of laughter on the inside. I just want to hear your opinions on this (im up for a good laugh aswell). As manufacturers claim bed covers will gain you a few mpgs. I myself havent tested, as conditions are really hard to replicate.

thats what i had going thru my mind. but when the guy your talkin too is twice your size, and thinks he's right. all ya gotta do is laugh.

i couldnt see having a hard cover though. The topper on my other truck is nice, but downsides too. Cant fit the bbq grille in the bed (dont want to lift it that high either) along with a few other taller items.
