That's a "trailer tail" setup.
MVT (Messila Valley Transport) has nearly all of their trailers outfitted with them. They have been around for about 3 or 4 years now but few companies are using them.
The idea is that they direct the airflow into a stream as opposed to the normal twin opposing vortices which are the norm and thereby reducing the drag of the trailer by changing it to a more laminar flow.
I really don't know if they work. I do know that the side skirts (air tabs) DO work to a degree.
Here's the company that makes them: http://www.atdynamics.com/
