Thank you for posting your story BaitMonkey. For years I have had only 1 chain; I can't remember why I changed it but for some reason, I did years ago. I knew it wasn't right but it worked, so I left it. Well, I read this thread, drove my arse down to Lowes and picked up another bolt and put my other safety chain on the way it was supposed to be. I feel a lot better about my trailering safety now. Thank you
