What are the Tennessee trailer's safety chains and gate hinge pin fastening requirements?
My wife recently inherited a utility trailer with the safety chains welded to the coupler and a gate hinge pin with a broken weld. I want to relocate the chains and repair/replace the gate hinge pin. How are Tennessee trailer's safety chains and trailer gate pins required to be fastened? Shall the safety chains be permanently fastened to the trailer tongue by bolts, anchors, welding, or either? Also, shall the hinge pin be bolted, welded, or either? Welding is my preference but I don't weld. If possible, please provide the links to the Tennessee regulations.
