I found it much more enjoyable fixing the problems of "LIFT" over those of "DRAG" but think I found a happy compromise between the two.
That spoiler you are thinking of might be better placed atop the cab roof, just thinking out loud.

That was an interesting read. The roof spoiler is similar to what I'm looking at doing. The high pressure reaching further back towards the rear glass looked like it was doing an effective job of eliminating the rearward suck inherent in that area of a pickup. That's probably what the OEMs are trying to achieve on the tailgates of the new trucks with those huge plastic tailgate caps.
On the front tire area, my Durango has these small spoilers in front of the tires. This picture shows what I'm talking about. I am planning a set for my truck.
Also considering stealing the attached pics from the new Tahoes. As you can see through the sideways pictures that I don't know how to make right side up, those little vents are not just for styling, they actually pump air into thee wheelwell area. If you zoom in, you can see asphalt back there.
