I made it just a few hundred yards from the shop, and when I bounced across the RR tracks, it came off the ball. Luckily the chains did their job, and I just have some dents in the bumper, where the tongue slid under it while I was trying to get stopped.
What had happened, was I have one of those universal 3 ball hitches, that slides into my receiver. My guys weren't paying attention and left the 2" ball up, when the trailer has a 2 and 5/16th coupler.
I was lucky but ALWAYS do my own coupling after that. It just takes one little thing.
