Abstract: A lock assembly for use with conventional fold-down bed doors of recreational vehicles is disclosed. The lock assembly draws the bed door down into proper contact with the door seal, as well as, securely locking the bed doors in their vertical closed position. The lock assembly includes a lock cylinder, a rotor, latch part and key. The lock cylinder is mounted to the bed door, with the rotor journaled inside. The latch part is operatively connected to the rotor so that it moves into progressive contact with a strike plate as the rotor is manually turned by a key. The latch part applies force against the inner edge of the strike plate to draw the bed door down against the door seal ensuring proper seating and closure of the bed door.
