Aerodynamics of Open Big Rig Trailer Door

On my way home from work tonight, I was getting on the freeway and had to merge behind a big rig. Nothing special except that the trailer door of the big rig was wide open (it was one of those roll up doors, not the two swinging doors). It got me to thinking what the aerodynamics of having the open (or even half open) door is. Does anybody know what will happen with the door open or can somebody do a quick simulation in Fluidworks or something? Will it cause more eddy currents to be created inside the trailer, thus increasing drag?
