Shortly after starting in this business with the first contractor I got a turnover ball because we were to deliver new Big Tex goosenecks on back hauls. The ED could do an empty goose neck trailer. Anyway it fell through. I have only ever moved one GN trailer with it. I then bought the steel Anderson 5er attachment to give me the option to be able to move a smaller new or dry 5er. But have never used it. I have the 6.4 bed but gather that some 5ers can still be a risk of hitting the cab. Anyway so I appreciate to hear your experience even though it's not using a HD.
