  • Patent number: 6125480
    Abstract: An extension member is attachable to a trailer hitch and extends away from the vehicle and is connected to a seating frame supporting a toilet seat. This extension member serves to provide distance between the toilet seat and the vehicle. The seating frame consists of a background which is perpendicular to extension member and two arms which extend from the back rail. The back rail and arms create a generally "U" shaped frame. In the top surface of the back rail are two mounting apertures. These apertures are 51/2 inches apart which is the standard different distance of the two mounting bolts commonly found on standard toilet seats. The toilet seat can be used by hunters, fisherman, campers, construction workers, boaters and other people who find themselves away from conventional bathroom facilities.
