Well I got a trailer about 2 weeks ago, I took one look at the safety chains and knew that they would have to be changed. Unfortunately I hadn't had time yet. Well sure enough yesterday I was pulling out of my own driveway the hitch wasn't properly set down and the trailer came off, and the chains broke and the wiring pulled out of the plug. Actually the poor weld broke on the chains. I stopped, and they realized that the trailer was about to pass me, so I moved forward so that it wouldn't hit the truck. Needless to say, safety can't wait! I rescheduled the job I had yesterday, fixed the wiring, added a break-away system and this morning I have a guy welding me on some beefier chains. I also bought a pin to put through the hitch lever to make sure that it stays in place, and to remind me to make sure its in place.
