While I think doing things a certain way just because its how it was always done explains alot (like why all truck cabs don't look like the airflow bullet truck, for example), there is actually a legitimate reason for the shape of the trailer:
The actual metal box, the "container" is not permanently attached to the frame and wheels. It can be detached with a crane. And then loaded onto ships, trains, hauled around the world, and then put onto a different truck in another country.
So they all need to be standardized worldwide, and they need to be able to fit tightly side-by-side so that 1000 of them can be packed onto a single cargo ship, which has a holding bay with racks and rails designed to fit standard sized trailers.
