It is a horizontal "slot", if that is what you are talking about.

My thinking is the the height above the back of the van will be pretty critical, sizing this gap. Right now I have it about 1.5" I think (will check later) above the back, which has it still sitting lower than the high point on the top of the van, so no additional frontal area. It's not too hard to adjust this gap though.

One of these things is not like the other. Being below maximum camber doesn't mean much, the air will follow down to the back edge, the encounter an 1 1/2" slot that leads to an internal duct with interference drag.

Maybe someday you will have done some fraction of the work aerohead has done. Which informs his comments.
