Extender for vehicle sewer connection

A sewer extender comprising:

• a tubular main body having a proximal end and a distal end;
• an adapter affixed to the proximal end of the main body and configured to couple to a sewer connection of a vehicle;
• the distal end of the main body having a plurality of external threads, the plurality of external threads comprising a base section of circumferential threads and a plurality of thread segments that are defined by a plurality of spaced-apart relief cuts, the base section of circumferential threads being integrally formed with the plurality of thread segments;
• each of the thread segments in the plurality of thread segments being defined by the relief cuts each comprising a recess having a wider base opening and inwardly tapered spaced-apart edges extending to the tip of the distal end to form a narrower opening that is coextensive with the distal end;
• the external threads being inwardly tapered, wherein the base section has a first circumferential dimension that is larger than a second circumferential dimension around the thread segments;
• a tubular telescoping body adapted to slide into the tubular main body via the distal end, the telescoping body having a proximal end, elongated walls enclosing an interior cavity and a distal end of the telescoping body, the telescoping body further comprising a coupling affixed to the distal end of the telescoping body and configured to couple to a hose or ground sewer connection of a ground location;
• a compression nut having tapered internal threads that are configured to threadedly attach to the plurality of thread segments;
• the main body comprising three inch inside diameter ABS pipe and the telescoping body comprising three inch outside diameter aluminum tubing.
