Just wondering if the strait up roof raise would hurt me at all
Define hurt — 10mpg vs 11mpg?

A lot depends on the floor plan of the interior, but your first example has a saddle-shaped curve. The ideal is a bluff prow that transitions smoothly into center section. It's not really bad it's just pointless and robs interior space.

Make it like an Airstream or U-Haul trailer.

Since you posted in Aerodynamics note that the front is only 25-30% of the total drag.



Tow vehicle you say?
