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.

Well I can get around 19.5-20 MPG at 60-65 MPH bobtail on the highway with 4:10 gears as pictured above, so I do not think that air flow effects much on big heavy diesel pickups. With golf clubs in the V-box, tools and eu-1000i in the big box, hitch and two of us, we are around 7200 pounds. Chris
