A cargo van door system comprises a cargo van with a cargo compartment, first pivoting means to permit one or more doors releasably to pivot laterally and perpendicularly in relation to one of three outward facing side walls of the cargo compartment to act as a door, second pivoting means to permit the door releasably to pivot perpendicularly in relation to a floor of the cargo compartment to act as a ramp, and means to coordinate engagement and disengagement of the first pivoting means and the second pivoting means. When the first pivoting means is engaged to permit the door to swing laterally and perpendicularly in relation to one of the outward facing side walls to continue to function as a door, the second pivoting means is disengaged, and when the second pivoting means is engaged to permit the door to swing perpendicularly in relation to the floor to act as a ramp, the first pivoting means is disengaged.
