Abstract: A multi-function utility vehicle has a structure and mechanism which allows the vehicle to carry people on a rear-facing seat, and which can quickly and easily be converted to carry cargo on a rear cargo area floor and at the same time carry vertically oriented cargo, such as garbage cans or golf bags, or can be quickly converted for carrying long horizontally oriented cargo. The conversions can be accomplished without removing or adding equipment, and without using tools. A rear mounted cargo area includes a horizontal seat and an associated seatback. The seatback is pivotal to be folded down onto the seat, and the seat and seatback are pivotal about 90 degrees to form a cargo restraining structure, and about 180 degrees to form an extended floor.
