I was talking to a fellow with a truck like mine, pulling a 5th wheel larger than mine, saying that he gained 1 1/2 MPG by replacing the tailgate with a louvered one. Does anyone confirm that ?
Agree with the fuel mileage not increasing... all hype IMO.
A few weeks ago in a Georgia state park I saw a tv with a louvered V tailgate that resembled an out of shape pretzel... looked like he unhooked and the pin somehow caught the gate a yanked it way out of shape... maybe turning too sharp while pulling out from under the 5ver ???
