The Trail King MG-HG is a precision-engineered detachable gooseneck for operators who know that standard equipment is usually not enough. It arrives field-ready and, by Trail King's account, loaded with more standard features than any other trailer of its kind on the market. Its frame is designed to take the torsion of heavy machinery without compromising long-term structural integrity, across four models from 60,000 to 90,000 lb concentrated capacity.
