If the dolly has brakes, wouldn't know why not, The GCV is quite heavy, but hitch weight on a dolly is near nothing, I towed a 2011 for 1 year on a 3500 lb hitch and had no problem. The owners manual mite say not advisable. But if you leave the tranny in neutral while strapping down, then put it in park as the very last thing you do, there will be no stress against the park mechanism in the tranny, which was the concern in the owners manual.
