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...
Maybe somebody else has access to the full study but I seem to recall that there was a difference between short bed and long bed trucks. The short beds would come out better with tailgate up and the long beds better with tailgate down.
