Question:
My camper has a trail air flex air fifth wheel king pin. Looking at a FOrd that has the factory good neck set up in the bed. Is there a 5th to goose neck adapter that would work with this set up?

Hi Steve; a Trailair Flex Air Pin Box like # LC328484 cannot be used with a gooseneck adapter of any kind according to Lippert. You will have to use a traditional 5th wheel hitch or you can swap out the pin box for something like the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR which fits Lippert 1621, 1716, 0719, Rhino, and Fabex PB 600 bolt patterns.
Does your Ford have the puck system along with the gooseneck? If it does, I would be happy to make a 5h wheel hitch recommendation if you can let me know the year and model.
