As I am finally going back to work for a short time (re-fueling outage at a nuclear plant) I have decided to start with the mounting system for the cap. If it works like I had envisioned I will use it on the new bed and attach a flat cover for the time being. In my head it works well and I have started taking pics of the process so I can share them when I finish. I have not bailed on the aerocap idea in the slightest. The mounting system is much easier to work on and can be used (hopefully) for many different types of bed coverings. Working 12 hour nights sort of puts a crimp in my construction time and if all goes well a flat cover will help until I get the full cover finished. The material I use for the flat cover will probably go to making a belly pan of sorts or the wheel arch fillers that I want. I hope to order my sheet of aluma-lite for the temporary cover on tuesday. I think the mounting system will alleviate some of the problems with being able to access the bed once the full cap is on. It should work for anyone that is interested in doing a cheap and easy "tonneau" or "half-tonneau" also. Wish me luck. I'll keep you all updated.

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.

Hm... Well, I could try my hand at photoshopping, or somebody else here could.

Hold on a few minutes.

Well, you could guesstimate by printing out that image, and using a ruler. Guesstimation will not by itself really affect the shape, as long as the general shape is followed.
