Abstract: An adjustable trailer hitch device that is affixed to the undercarriage of a vehicle so as to be supported by the chassis and bumper mounting brackets thereof without modification, welding, drilling, or bolting. The hitch is adjustable as to width, height, and depth, and includes a retractable tension cord having a hook at the end thereof for hooking onto the chassis. The tension cord is tensioned by winding or reeling, and also by extending the length of a vertically oriented compression member extending fore of the vehicle from the aft section of the hitch so as to apply an increased force to the underside of the chassis of the vehicle. A pair of vertically and horizontally adjustable jaws retractably grip the port and starboard bumper mounting brackets of the vehicle which, with the hook, attach the hitch device to the chassis of the vehicle.
