A fifth wheel hitch has a base attachable to a towing vehicle, a seat attachable at a selected elevation above the base, and a kingpin adapter attachable to a kingpin of a trailer so as to permit rotation of the kingpin adapter relative to the kingpin about a kingpin rotation axis. The seat has a mouth which narrows in the longitudinal direction, such as by having a pyramidal shape. A bottom of the kingpin adapter has a shape which can cause both pivoting rotation of the kingpin adapter relative to the kingpin and longitudinal or transverse translational movement of the kingpin adapter and attached kingpin when the towing vehicle is driven to a position with the seat under the bottom of the kingpin adapter and the kingpin is jacked down so the kingpin adapter seats into the seat.
