In all my towing years 50 or so I have had only one trailer come loose and that was my stupid, I did not latch the hitch lever!!!!!' The safety chains caught it in the X like they were suppose too and I was able to get it connected.... the right way. This trailer is so lightweight I did not even think I was towing anything. My pickup has disk brakes all around. Oh and now I see its in the new recall, time to visit the dealer for the reprogramming.
