Abstract: A front tow extended saddle is disclosed. The saddle allows a first towing truck to mount a second truck, facing forward, behind the first truck, in order to tow the second truck to a distant location. The saddle allows the towed truck to face forward during transport, thus allowing for the normal loads and stresses of movement on the towed truck. This configuration is preferable to movement with the towed truck facing-rearward, in which the typical aerodynamic surfaces of a large truck act as a drag during transport, imposing high wind loads and unusual stresses. The front tow extended saddle is also designed to minimize the required vertical rise on the towed truck, which also avoids additional stresses during loading and unloading onto the towing truck.
