Claim:
1. A rear aerodynamic drag reduction system configured to be coupled to a rear frame assembly of a trailer including a rear frame and a rear swing door, the drag reduction system comprising: a main wall panel configured to be coupled to the rear frame assembly to extend generally rearwardly of the trailer at least partially along a height of the trailer, wherein the main wall panel is movable relative to the rear frame assembly between a deployed position and a stowed position; a secondary wall panel configured to be movably coupled to the rear swing door of the trailer to extend generally rearwardly of the trailer at least partially along a width of the trailer, wherein the secondary wall panel is movable relative to the rear frame assembly between a deployed position and a stowed position; and a locking mechanism configured to releasably couple the main wall panel and the secondary wall panel to each other to prevent relative movement between the main wall panel and the secondary wall panel when the main and secondary wall panels are in their deployed positions, wherein the locking mechanism includes (i) a latch coupled to the one of the main wall panel and the secondary wall panel, the latch defining a slot, and (ii) a pin coupled to the other of the main wall panel and the secondary wall panel, wherein the pin is received within the slot when the main and secondary wall panels are in their deployed positions, and wherein the latch extends downwardly below an inner surface of the secondary wall panel and the pin extends upwardly above a top edge of the main wall panel when the main and secondary wall panels are in the deployed positions.
