Nope, but it was cheap to make and try out, which is a big plus for me.

The carry box is probably not helping the FE that much since the weight of it is probably offsetting any aero gain.

My cargo box in the bed might weight 40-50 pounds empty. I carry very little in it. It is mainly there because having a single cab doesn't give me anywhere to carry stuff out of the weather.

The top was just a simple plywood shelf which extended from below the 3rd brakelight straight back 18-inches.If you laid a straight-edge off the back of the cab roof,down to the top rear edge of the "shelf" that angle was around 12-degrees.Wood gussets provided rigidity.Drywall screws held the whole thing together.House paint kept it alive for years.
No attempt was made to provide a curved skin or any complex shape at all.
Not real pretty but the air was okay with it.
Fuel records indicate that it performed as Texas Tech had reported.

Thanks Phil, I'll have to see if I can locate any photos of that.
Straight back off the Cab roof, under the 3rd brake light would be very easy for me, the small structure I mount my antennas on is already located there!
