Abstract A system for aligning a leading vehicle with the vehicle to be trailed, the leading vehicle being of the type having a rearward window facing the trailing vehicle and a rear hitch for attaching a tongue of the trailing vehicle thereto. The system includes an indicating mark on the rearward window, and a rod mounted on the tongue of the trailing vehicle, the rod telescoping in both the vertical and horizontal directions such that the dimension of the rod may be adjusted so that the extremity of the rod comes into contact with the rearward window immediately adjacent the indicating means when the hitch of the leading vehicle is in alignment with the tongue of the trailing vehicle.
