Well, what do you know! "This writer spent 5 minutes researching this.... How about leave your tailgate up, you get better mileage. People think it is dragging in the wind, but it is drafting behind the cab and actual has better air flow than when down, and when down you are hurting the rear structure as the gate stiffens the rear of the bed. A truck cover is better yet." That's partially true GearGuy, but every truck and model is different. I know that personally as my 1987 Dodge Dakota got better mileage with the gate down by almost 10%. A bed cover does better still as you said. No reason trucks can't get 25 to 50 mpg and more if they do various modifications as I know or know of others who've done quite a few things and are getting anywhere from 30 to 55 mpg out of them.
