Abstract: An accessory support system attachable to the exterior of a motor vehicle supports recreational accessories such as grills, table tops and umbrellas for use out of doors. The system comprises a lateral support assembly adapted to connect to the trailer hitch of a motor vehicle, and one or more vertical support means adapted to engage one or more recreational accessories such that the accessories are supported in a position suitable for use. The lateral support assembly may include a first lateral support rod adapted at one end to removably engage a vehicle trailer hitch and adapted at the other end to rotatably couple to a second lateral support rod via a vertical coupling means. The second lateral support rod can include a distal end portion adapted to engage a vertical support rod which supports grill means. The grill means may be positioned within about a 270.degree.
