Do "vented" tailgates help on 5th wheels?
Friend of mine says he gets better mileage with a vented/louvered tailgate. Do they really make a difference or is it just another novelty item that's nice to have but not needed.

Ever see the Mythbusters episode where they tested mileage on a truck with both tailgate on and off? The truck with the tailgate on got better mileage. MYTH BUSTED...
I wish they had done a test with a 13' high wall above the bed pushing all that air into the bed :W
A must have? no. More MPG most likely a toss up. Make hitching up easier? yes
