As I take it the rear would be much more important than the front. A blunt raise would alow my to mount a big screen TV above the driver head. But if its beneficial I could slope the front as well and live with a small screen.

* With no leading edge radii a bus will be Cd 0.88.
* With leading edge radii equal to 5% of the square-root of the frontal area, the drag will be Cd 0.36.
* With the 'Stromform' front, Cd 0.34. And the most difficult and expensive build.

* Test data exist for buses with 5-degree boat-tailing, at top, sides, and bottom. The further back, the lower the drag. Diminishing returns at some length.
* If 'soft' edges are incorporated into the tail, you can kill off any potential vortex drag.
* If boat-tailing is done as an 'add-on', the legal limit is 60-inches of added length.
