I can't find the post, but this was on an early version of The Anal Probe:

The setups on the backs of 18 wheelers these days are a good example. Crappy boattails, but way better than the unmodded truck:

It's not pretty, it's not optimal. It's a box.
those are actually illegal anyways in most states

and if the cop is a real jerk he will cite you for a oversized load without permit as well

I really love tailgating those the FE is a bit higher compared to a normal 18 wheeler truck
