Demco 6330 5th Wheel Hitch.

This hitch takes care of tight-turn clearance all by itself. The automatic slider gives you 22-1/2" of travel front to back, so when you make a sharp turn, the head glides toward the tailgate for extra cab clearance and then slides back into position when you straighten out. You don't have to pull levers or get in and out of the cab to make slow-speed turns--everything happens smoothly through the built-in roller-and-guide assembly that moves as your trailer turns.

A single-piece wraparound jaw completely surrounds the king pin for 360-degree contact. That tight fit means less rattle and less chucking on the road. A 3/4" thick solid steel locking bar backs up the connection for extra peace of mind. Once the jaw closes, it automatically locks into place, so you know your trailer is secure and ready for towing without any second-guessing.

Every truck and trailer combo rides a little different, so this hitch gives you three height settings--15-1/4", 16-1/2", and 18"--to get your trailer level and maintain proper bed rail clearance. The side plates bolt directly to industry-standard above-bed rails, locking in with included safety pins. Once mounted, you can raise or lower the head height as needed without hassle.

Like new.
