Air drag on our trailers and 5ers comes as much from the square corners as anywhere, especially at the back. You can V the front and curve the front cap, lean it back and curve the top, etc... but it's only a small part of the equation... Truckers are adding panels to the backs of their trailers, and along the bottom in an effort to tame that airflow down some, and make less drag. If they can save 2 or 3 percent in fuel, it can add up to big bucks... like the winglets on jet liners.
