I've had a few people ask about my wind fairing. I used a piece of scrap 1/2 inch plywood. It measures 48 inches by 11 inches. Since I used scrap wood, 11 inches was as tall as I could make it. It's attached to a Yakama crossbar using 3 U-bolts with fairing stirps acting as extra bracing. I then coated it with spray can bed liner.
If I was to make it again I would make it about 15 inches tall so that it extends all the way up to the roof level. I would also consider coating it with fiberglass and maybe using thinner plywood.
I have never scientifically tested how much it helps with fuel economy. I would guess about a 1 mpg increase in mileage. In addition to the gas mileage benefit, it also helps deflect branches to the roof of my camper rather then having them slide inbetween the cabover and the truck roof.
Here are a couple of pictures.
