Do you want to haul mostly live stock or horse type trailers? If so, you'll likely find most are goose neck trailers, which is a ball hitch.
Where as a fithwheel is a kingpin hitch. Typically used in heavy trucking.
While there are adapters available, if your goal is a goose neck, an actuall goose neck hitch is much handier. Typically leaving the bed free to use openly. Where as a fith wheel will either be above the frame and permenetly in the way or have to be removed and stored to use the bed. Posted via Mobile Device
