Thanks for all replies, please keep suggestions coming.

Rear corner airflow trip feature - permalink
Airflow along the side of a vehicle tends to follow the curvature of the tail lights and bumper part way around to the rear of the car, which can cause more drag than a sharp corner "crease" that promotes clean separation at the trailing edge.
GM designers integrated such a crease at the rear of the Chevy Volt "production" concept, a feature that could be retrofitted onto existing vehicles.

Correct....in fact in the Hybrid version of the GMC Yukon, you will see that it uses extensions on the rear pillar and sharper profiled tail lamps to promote clean separation.....its a slight difference that the casual observer may not even notice. The regular Yukon is rounder.
But don't forget in your application you have vents/flaps where the tail lights normally are that feeds air into where the potential turbulent wake would be.....so I don't think its really an issue for you....again this can be tested using tufts.
It really is too bad that they don't allow for smooth under-bodies and rear diffusers...you would have a venerable guided missile if they did.
