For the aerodynamics guru(s). If one were to fab scoops on either side of the coach at the rear, ducted them to an A/C compressor.condenser module, and exhausted it directly behind the coach, would the scoops not be in relatively higher pressure than the heated air centered on the rear of the coach, forcing the correct airflow through the unit even though it's situated close to the bodywork? You could get a split setup inside the bumper.

I'm not an aerodynamics engineer or anything, but I think a NACA duct might be better than a scoop for what you are describing...

Being an Aero/Mechanical Engineer, they never teach us thes practical
things, that is why engineers are not always very useful until they
specialize and learn from hands on people.
They cram us with high power equations and try to weed us out as too many
engineers looking for work lowers the salery .
I learned practical aero from technicians and ones that specialize in
certain application.
