I think the swivel hitch is good safety thing... i once heard a riderIR Harry said:I don't think it makes any difference. If you are tipped over so far the round ball hitch is going to hit the stops, you have a bigger problem than a trailer hitch. Besides, with a swivel hitch, its one more thing to go wrong. They have been known to come apart. And ball hitches have been known to come off.
