Nut backed off ball caused accident

69 Avion brought up an interesting point. I have a neighbor that I have had issues with a long time. I mean it's really pretty bad..I had left the trailer hooked up to the coach on the side of the house for 2 night while we loaded and got it ready for the trip. I alway do a pretrip inspection and every thing looked fine. It would not take much loosing to make that nut back off. Anyway i have no proof that the neighbor did anything like that but they are crazy. I just feel that everything was right on departure and I can't explain what happend. I mean you would think with a the nut backing off, the trailer would moving all over the place traveling down the road. It did not I continually check the camera for issues with the tow. I didn't see it move until it poped off. As far as the negative comments I really don't take them as such. I think this kind of talk is helpful for anyone who reads this. Accidents can happen to anyone awarness and preventive measures reduce the chance of occurance. This post is a form of awarness. I have towed a boat,car dolly, utility trailer with motorcycle for many years without issue. this time it caught up with me. Thank you all for your comments
