The system also includes a mechanism for positioning the pivotable and extendible ladder rack assembly in a first locked down position of the ladder rack, a second tilted position, and a third tilted/extended position for loading and unloading a ladder. A cable is coupled to the one end of the pivoting member and a cable-spooling mechanism pays out and reels in the cable for positioning the motorized ladder rack.
