Well, get a great big wind tunnel? :^)

Or

Look at the inverted spoilers on the backs of SUVs and old station wagons.

that's funny because i'm right in the middle of putting ladder racks on my
pick up truck cap. *i have an piece of streamlined aluminum airplane strut
that i'm going to use for the horizontal. *i was wondering if that might
kinda break the boundary layer. *doubt it. *hafta check with a wind tunnel,
which i have none.

b.w.

Anything you do to reduce drag translates into dollars and cents
saved...fast.

I reviewed a report once (sorry I don't know where it is now) that
showed how just a little drag reduces gas mileage quickly.

I was surprised by how fast the effect showed up.

Lesson learned....keep your rigs as areodynamically clean as possible.
