1. A cargo van door and ramp system comprising:
a frame adapted to be mounted in an opening in at least one of three outward facing side walls of a cargo van cargo compartment;
the frame comprising at least a horizontal base and two upright side arms extending from distal ends of the base;
two door-ramp components mounted side by side to the frame, the door-ramp components adapted to function as either doors or ramps;
the door-ramp components releasably attached to each other at an inner edge of each door-ramp component;
the horizontal base and two upright side arms comprising two L-brackets releasably connected to each other adjacent a floor of the cargo van cargo compartment and centrally of the opening which, when connected, permit the door-ramp components either to rotate horizontally to act as a door or to permit the door-ramp components to open and close together as a ramp, and when disconnected, to permit either door-ramp component to rotate vertically to act individually as a ramp;
the door-ramp components and the frame are releasably latched to at least one of the three outward facing side walls of the opening adjacent an outer edge of each door-ramp component and held in place in a closed position by latches, at least one of said latches engages each door-ramp component adjacent the outer edge of the respective door-ramp component and at least one other of said latches engages each door-ramp component adjacent a bottom edge of the respective door-ramp component;
each door-ramp component hinged adjacent one of the upright side arms to the at least one of the three outward facing side walls of the opening by first hinges and adapted to swing open and closed horizontally to act as a door when the respective at least one other of said latches is released;
each door-ramp component hinged adjacent the horizontal base by second hinges and adapted to swing open and closed vertically to act as a ramp when the respective at least one of said latches is released; and
means to engage and disengage the first hinges and the second hinges.
