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
Agreed. Mythbusters did not do a test with a fifth wheel attached. The airflow is vastly different in that case. I have had things sucked out of the bed with a solid gate. With my current gate (made out of steel tubes), nothing in the back of the truck moves so much as an inch as long as the fiver is hooked up. With the bed empty, it's a different story.
