Nice concepts. Just wanted to point out in case everybody didn't already know, that you don't want the cap to actually touch the back of the cab and literally seal the gap. If you've ever ridden in the box of a pickup when it's going down the road you'd be amazed at how much relative movement there is between cab and box. Of course if one really was concerned about that gap they could try some thick weatherstripping... it might make annoying squeaky noises tho'...

Two summers ago I started a coroplast aerocap for the F150; mine only uses simple curves. I didn't finish because I was out of state for 6 months and I ran out of Coroplast. Maybe this spring...
