I have a king pin extension for sale. This extension is made by POPUP INDUSTRIES, model RV5. See: (
http://www.popuphitch.com/rv5.htm). It is very heavy duty and mounts on the standard king pin of a fifth wheel trailer. It extends the reach by 10 inches. This unit will handle a trailer up to 24K lbs and a hitch weight of 6K. This is a great accessory for towing a fiver with a short bed pickup truck if you don't have a sliding hitch. I bought this kit three years ago for my SOB but don't need it for my Monty. This kit has ALL the hardware and paperwork and is like new. It's painted bright white but can be painted black if you desire. Unit can be mounted in about 1 to 2 hours using a drill and wrenches. A torque wrench is necessary for proper installation. This unit new sells for $400.00, I'm asking $250 plus shipping (about $40). Email me direct if interested:
