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.

I wonder how the air flow works when you have a 5th wheel hitch in the bed breaking up the flow? I doubt it makes any difference at all with the 5'er hooked up. Without the 5'er I would think that the 5th hitch would disrupt the air flow enough to not really matter whether you have a V type or reg tailgate.
