Last year just before climbing Monarch pass in Colorado I felt a jolt. Looked in my driver side mirror and saw the Tahoe. Whoa Nellie! Looked in the rear camera and saw it swaying back and forth. I gently started slowing down, it helped since I was starting up the incline. Safely got to a safe spot to stop on a shoulder. Walked back, almost fell off the embankment climbing out, and saw the driver side towbar arm just hanging. The pin that connects it to the Tahoe was missing. Thankfully nothing was damaged other than a few scratches on the towbar arm. It was one of these cinch pins with a nice pull handle that I recently bought from Harbor Freight: https://www.harborfreight.com/58-in-easy...63671.html
I replaced both pins with a couple old tow pins I had and bought a new set from Blue Ox. Yes, I threw away the HF ones.
So best practice is to inspect your tow equipment and if you have any doubts replace parts. Especially the pins since they are subject to stress and are the weak links in your tow system.
