Wing thoughts for my pickup...

The guy is in NC and he built mine in fiberglass off of my original bumper. It probably weighs 3-4 lbs tops. I can get you hooked up if you need one.

I like to fly low in the Desert, with an open bed, airflow is turbulent though predominately flowing towards the cab at speeds from about 60 to 125. Above that point air flow reversed, however the bed area was low pressure. The only laminar air I found was about 10 inches higher then the cab above the tail gate. Sheetmetal was mid 70's, low pressure in the bed area would start unloading the rear tires at about 130 and nobody wanted to go over 140. You might not notice the unload on pavement but in dirt, the rear tires would spin, you could see it in the Tach almost before you could feel it.
Do you actually get enough air flow, in the right direction at bed height to do anything? Is it the bed cover that you feel is necessary?

Crap, if I had been thinking I would have also drawn the outline as if the bed wasn't covered and had a closed tailgate......damn brain fart.
