Our Ultimate Connection was tested, designed and passed the certification to be classified as a 5th wheel hitch – for which the vast majority of the laws in the United States only require the break-away switch to be used as the safety system needed. The only state that we are aware of with more specific laws is Indiana, which has written the law to state that any trailer coupled via a tow ball is required to use safety chains. We offer the safety chain set as part # 3230 to satisfy the cautious towing individuals and to appease the laws of Indiana and any other state that may have the same law that we are not aware of.
