Has anyone read what the manufacturers say about any advantage of driving with the tailgate down on a pickup to reduce wind resistance...and hence fuel consumption. Thanks for your response.
I read an article in Popular Science (i think that was it) and it's been shown to have little if any effect on MPG. If I remember correctly, it only made a tiny difference on a single cab with a long bed.
Oh, and welcome to FTE.

it will improve mileage, however it'd be no more than 1-1.5 mpg which isn't much considering that per tank is usally within a 2-3 mpg differance based on driving condition.
Oh Lord,
There has been a million and a half topics and posts about this very argument. If you search, you will find a plethora of information about this.
You will find everything from where the wind focuses on the tailgate, to the cost of a new paint job for your tailgate because of the stone chips, to the loss of integrity from the removal of a body panel...
Enjoy,

YOUR REPLY:
Which manufacter said to drive with the gate down?[/QUOTE]
RESPONSE: None, Sir: I'm sure the manufacturers have the answer. From the responses just now, one says the improvement is negligible, the other says maybe about 1.5, mpg... Thanks...
Your MPG will be less with the tailgate down because of more wind drag going across the bed. With the tailgate up the wind comes over the cab and hits that air pocket in the bed and goes over the tailgate. This was from an article I read in motor week done in a wind tunnel. Just think about that coffee cup you left in the bed blowing around in a circle, that is the pocket of air I am talking about.
