They (Volvo) have done a great job with the aerodynamics of there semi's, I wonder if they make a aero tailored trailer, as that trailer could use side skirts with wheel cover panels. That would help with your rig,although chances are you would be picking up and dropping off various trailers. Your rig looks sweet, I like the look of the improved aerodynamics.
a quick idea is too make aerodynamic mirror fairings to flow the air around the mirrors smoothly.
