The classic response to your inquiry is that drag is created at the aft section of the vehicle, after the high point in the roof (at the rear).

However after looking at your "brick" I see there is ample opportunity at the front where attachment of the air built up from air pressure occurs.

The air pressure build-up after the cabin as it hits the box is off the scale, those rounded corners help, but I cannot but help to feel your pain.

Let me try and sketch something up, a picture is worth a thousand words.

EDIT:
I marked up eight things off the top of my head, looks like a lot of work. If you are going to do that much work, look at the Ram-Aero camper thread of a few days ago.
