Abstract
A trailer hitch for a vehicle includes an attachment bar and post for attaching the hitch to a vehicle and a base suspended from the attachment post to allow limited lateral movement of the base with respect to the attachment. A universal pivot connector, such as a hitch ball, is mounted on the base to move with the base for mating connection to a tongue of a trailer to be connected to the vehicle. The trailer tongue is biased against rotational movement with respect to the pivot connector whereby the allowed lateral movement of the suspended base and the pivot connector and the resistance to rotational movement of the trailer tongue with respect to the pivot connector combine to move the effective pivot point of the tongue on the universal pivot connector approximately to the center of the rear axle of the towing vehicle to simulate the towing movement of a fifth wheel trailer hitch.
