Correct- I just attach the rope to the frame of the truck...and drive ever so slowly! You really do need to have a 'feeder' and a 'spotter' for this job- and communicatio between them!
An VERY important safety note...NEVER simply loop the rope around a hitching ball. Those things can- and often do- shear, resulting in a hardened steel ball flying at someone's head like a bullet. There are regular fatalities from this practice.
