A door assembly to be attached to a cutout in the side wall of a recreational vehicle for alternatively closing off and providing access to an internal compartment. A body frame is attached to the cut out in the side wall. A door panel is attached by a hinge to the body frame. A pair of push button latch mechanisms, one of which contains an integrated lock, retains the door panel in the closed position. The locking latch may be switched to the locked position when the door is open, automatically locking the door when it is closed. A flexible seal, incorporating a double sealing surface feature, is attached to the perimeter of the door and seats against the frame when the door is closed. The door panel includes a separate door wall and inner and outer door frames which are joined by a retaining clip. The metal retaining clip has a return bent upon itself shape and pointed wedge shaped upset portions for joining the outer and inner door frames. The hinge is formed by portions of the frame and door panel that are flush with or recessed from the maximum protrusion distance of the door panel from the side wall, joined by a hinge pin that is not accessible when the door is closed and which is designed to break away if destructive forces are place on the door assembly.

A battery operated flush assembly for a portable toilet. The flush assembly includes a pump and motor mounted to the toilet's seat section. A battery pack is removably mounted to the seat section and includes terminals which, as a result of mounting, become coupled to the motor. The battery pack supplies electrical power to the motor and includes an actuator, protected from inadvertent actuation within a recess, for electrically closing the electrical circuit and causing operation of the pump to discharge flush water into the bowl. A check valve, located in-line with the discharged flush water, opens in response to the pumping of flush water and is maintained open with minimal line pressure to increase the life of the battery pack. An O-ring is also used to ensure that the battery pack can be easily removed and reinstalled with a fluid tight seal therearound.
