So, does a small angle like 10 or 12 degrees make that much difference? How does a straight-back commercial topper compare?
I was also looking at the half tonneau designs that basically fulfills all my requirements, (and looks even less like a spaceship). I was seriously considering this design until I finally read in a post that it has to be open in the front with a little space between the tailgate for the best aero, which doesn't work well for securing items in the bed.
Also, it's been a while so I don't remember where I read it, but I heard the vortices would relieve the pressure drag at the rear of the vehicle. And so why do aircraft use them if they create drag?
What's the proper application for vortex generators?
I'd appreciate some clarification. There's A LOT of information on the site, but some of it seems contradicting and confusing.
