Oh, why did I never think of it? I'll just pull one of those outta my back pocket...
I've towed many terrible things many terrible miles. Like an unbraked (brake solenoid failed) 16,000 lbs trailer with a dodge 3500 hauling 5,000 lbs of pallet sand in the bed...it was not that bad.
That said, even I would stay away from towing with that rig.
