I see all these wings and spoilers on suv's, and after searching, have found that the ones that FOLLOW THE CONTOUR are worth while, however, may not help a whole lot.
That being said, I didn't find much in the way of these type of things for PICKUP trucks. I know an Aerocap is probably THE best possible solution, however, it does have some drawbacks, not to mention, many people don't want a cap, or already have something, such as I do, since they need to lock up their tools.
So, would putting a SUV type spoiler be effective on a pickup to reduce turbulence?
Links for thoughts and discussion:
A pickup cab spoiler - seems to direct air DOWN behind the cab, which for a pickup, may not be so bad as it would reduce the wake behind the cab. Downside would be, obviously, the drag created by the wing-ish part being higher than the cab.

This design is mass produced, incorperates a wing and sides similar to a short aero-cap:

Last but certainly not least, this is simply a link to a Nissan Murano site, but the wing really looks like it could be the most promising of all I've seen on an SUV.

I don't know if any would be effectve really, and if they are, how much? If i'm not getting an aero cap, I may look into producing something?
