The difference comes if the hitch fails. Lets say your trailer comes off causes and accident and gets someone killed.Pelican18TQA4 said:The Bosal hitch is illegal because it is not DOT-approved. However, owners have installed European headlights and taillights without thinking twice and neither of these items are DOT-approved.
Your insurance company will not think twice about leave you stranded with the bill because that hitch is not DOT approved. It would be their way out.
Yes this is an extreme example.
