The hitch assembly comprises a hitch member, a shank assembly for attachment to the towing vehicle, a tow vehicle mount for attachment to the towed vehicle, and a hitch alarm. The hitch member comprises a drop ball mount, and a drawbar. The drawbar is secured to the undersurface of the drop ball mount. The shank assembly includes a shank, a ball mount, a pair of ballasts, and a coupling member. The shank extends through the opening of the drop ball mount. The ball mount has a threaded engagement with one end of the shank. Interchangeable ball mounts and the use of one or two ballasts enable the same hitch assembly to be used to tow varying loads. The tow vehicle mount is secured to the undersurface of the towed vehicle. The tow vehicle mount comprises a receiver tube secured to a vehicle guide plate. The drawbar is inserted into and through the receiving tube. The hitch alarm detects an unauthorized removal of either the hitch member or the towed vehicle from the towing vehicle. The hitch alarm is substantially hidden from view when the drawbar is secured to the tow vehicle mount.
