I wonder if there is any difference in gains between a longbed and shortbed with a cover like this.
The long bed truck would stand to gain more from an aerodynamic cover than a short bed if I am not mistaken. This is due to the fact that the air has more chance to get caught in the box and hit the tailgate rather than flow past the cab and over the tailgate. There are gains to be made in both cases however. I have a short bed as you can see.

It's too soon to post results yet, but my first run in very windy and cold conditions were netting me almost the same mpg's as I was getting in warm relatively calm weather.

More results to come......
