Abstract: A tailgate attachment used in combination with a pivoting tailgate of a vehicle, includes a back panel and a pair of side panels having configurations adapted to form a rearward extension of the cargo space. Each of the side panels is pivotally coupled to the back panel. The back panel is attached to the tailgate with a pair of hinge members secured between an inside surface of the tailgate and the back panel. The pair of hinge members are each comprised of first and second securing elements and an intermediate rotating member. The intermediate rotating member rotatably secures the first and second securing elements to each other such that the first panel may be rotated around the pair of hinge members from a stowed position to a loading position, approximately 270 degrees away from the inside surface. The first securing element is preferably attached to the inside surface of the tailgate in proximity to a top edge of the tailgate.
