Its going to be tough with a drop deck.
I agree, be careful with the tool boxes hanging up, skirting would be safer.
You are getting good mileage as it is, I'm impressed.
I wonder if you could mount a Kamm to your headache rack to get the airflow started down for the shorter loads. Perhaps it would hinge up and act as an air wedge/ramp for taller loads?
