Abstract: A gooseneck trailer hitch to couple a trailer torque to a towing ball mounted on a towing vehicle to be used in pulling a trailer has a tow member which is to be secured to the trailer tongue to extend generally horizontally forward of the trailer. This tow member has at its outer end a connector which pivotally mounts an arm for the arm to be swingable from an outwardly extending position into a vertical position with the outer end of such arm having a socket suitable to cooperate with the towing ball on the vehicle used to pull the trailer and locking means is provided to retain the arm in its vertical position. A jack stand is utilized adjacent the forward end of the trailer and tow member to hold the trailer and tow member generally horizontal incident coupling and uncoupling the trailer relative to the towing vehicle.
