Pull Rite 5th Wheel Hitch, Model 4100K rated at 16,000#. Along with mounting rails #4426 for 2016 or older F250 and capture plate. As far as I know, everything you need is here as it was removed at the dealer.
This hitch works great for ensuring that when you are under the trailer backing that you do not turn the cab of the truck into the trailer. Typical application is for short bed pickups.
I loved this hitch as it made towing and backing worry free, but don't need it anymore.
