Hi Darin,
I have made two with one in the mold. I intend to do a test market this fall after my contract is up. Glad I found ecomodders and thanks for posting the pics of the aero cap. I submit a couple more pictures of two other configurations the cap can be driven in. Aerodynamics go to pot but after you haul tall cargo or camp out you can change it back to the aero configuration.

Thanks Ben for the compliment. I hope if you do get a pickup truck in the future, the aero cap will be available to you.

Thanks for crunching the numbers. I have so many times too. If I had the money now I would be under way. Maybe something will break, but for now, the tax man cometh!
