Abstract: The vehicle mounted cargo van has a floor, rigid side walls, a rigid front wall, a roof and a rear wall. The rear wall is a door assembly that opens substantially the entire rear of the van. An elongated cargo opening is provided in one of the rigid side walls. The cargo opening extends upwardly from the floor about one meter. The horizontal length of the elongated cargo opening is longer than the length of the longest elongated cargo that is to be transported in the cargo van. An elongated cargo door assembly is pivotally attached to the cargo van for pivotal movement about a horizontal axis that is slightly below the elongated cargo opening. A latch assembly secures the elongated door assembly in a closed position. When the latch assembly is released, the elongated cargo door assembly pivots about 180° to an open position.
