You mean, like this?

You can see the aerodynamic template overlaid on the image of the Ford Ranger. Note how the proposed Ranger aerocap follows the roof of the aerodynamic template.

That template was devised by a hard-working fellow here who has done a lot of research and performed a lot of testing and modification. The template he devised has been shown to be the best general shape without having to do extensive computer modelling.

If we were to make the proposed aerocap to actually meet the tailgate, instead of following the aero template as it does, then aerodynamic drag would increase compared to the aero template cap.
