Tested with professional CFD software, the truck shows a .47 Cd.

The CFD software used in the pictures in this thread is from a program that was apparently created as an app for cell phones to give a very rough estimate of Cd.
It's fun to play with, but not very accurate.
I got a .41 when I tested the truck using the same software.
Adding mirrors actually decreased the Cd - I guess because the turbulence merged into the turbulence spilling over the sides and actually cleaned it up a bit.
Is that actually accurate ? Most likely a big NO.
