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've had a blue plastic tarp blown out of my truck while towing my 5er with stock tailgate but never had chocks or wood blocks come out. Just came back from a 510 mile round trip to Ohio at turnpike speeds of 60 - 65 mph. Maybe my folded trifecta cover helped.
