I liked the video,it's a good introduction to aero,thanks!---------------- All the car makers appear to be raising the height of their pickup's box rails in comparison to the cab roof such that curvature of the locked vortex in the bed better approaches the Kamm roofline.If you look at the drawings of the truck on the easel and of the smoke trace,they both mimic Ford's "aeroshell" of the Texas Tech paper published in the 1980s.---------- It would be interesting to place the F-150(with smoke) under the aerodynamic template and see what kind of "fit" might exist.Thanks again Darin!
