In hauling 5th wheel trailers is there a difference in fuel (gas) consumption by using a vented tailgate?

Haven't used one, but from what I've heard, there may be a little advantage, but probably not worth the cost of it. You could take off the tailgate, install one of those nets across, and you would reduce weight too! Probably as effective and less expensive.

See the myth busters. Use of mesh was the best. The next best was tailgate up. No tailgate at all, tailgate down and fiberglass lid on the bed were all about the same, but poorer mileage than the first two. Some people say they still like to run tailgate down because it blocks the view of camaras at intersections.

Gate on, gate off, vented, not vented, from what I've read it makes no significant difference.
Best thing you can do is shape your rig like a jet airplane.

The benefit of my louvered tailgate is that I don't need to drop the tailgate when unhooking - not any savings in fuel economy.

One great benefit of a 5th wheel "V" tailgate is NOT damaging it if you fail to lock in the kingpin when hooking up. Don't ask me how I know.

Myth busters said no gain with the vented tailgate. But I like my factory tailgate with Truxedo cover. When i'm not towing, nobody knows whats in my bed. Grocerys, generator, tools.etc. And mythbusters did say better milage with cover.

I once came across testing by Ford, which I cannot now find, that tailgate down there was a slight loss in mileage.
