Pick-up truck cabin top rear corners are similar to SUV roof rear corners in that air flowing along the sides and roof may be traveling different distances over different obstacles or surfaces.

What this means is there a potential for one plane of air to fold into the other because of differing pressures.

Having nothing at the corner leaves this state in it's original messy state (my design currently).

Having something at the rear corners I'm told at best can delay vortex formation not eliminate it.

As I have not yet repaired the mess Photoshop left us, it is difficult to discuss in the depth I would like to. And remember, the sickle shape roof wing I have is the result of using some scrap piece that just happened to fit. As an experiment I just wanted to see what would happen.

I don't claim this to be some stroke of genius just that it turned out to be non-invasive at the corners.

Phase-2 design studies call for side wings and big generous curves at cabin corners where side wings meet top wing. Very similar to the rear spoilers on econoboxes posted in the forum. They sort of look like hoodies.

This is the direction I would point Hat_Man to, just supersize what you see on the current generation of SUV's, one up them.

Manufacturer's stuff has to appeal to the masses and be car wash proof as well as survive the cost analysis engineering process where ever fraction of a cent counts.

Our projects can be what ever we want them to be.
