Not big but dumb. My buddy borrowed my trailer (yes, this is always how the story goes) to go pick up his mint condition CJ5, restored in 1995, powder coated frame, new everything, been sitting in a climate controlled garage since he moved to the US. Mom passed away so he sold the house where it was stored.
Grabs my trailer, goes to Lower Niagara, gets stopped at the border for no trailer plate. Must have fallen off or something. Truck gets searched, trailer gets inspected, gets through the door to syrup sucking hockey land.
This is a Kaufman 10k trailer, 2 5/16 clamshell style coupler, I take decent care of it, bearings checked and greased before every big trip, has tire sensors on it, painted all the same color, it's not sketchy.
So he runs around up there for a couple days and loads the Jeep to come home. Blows a bearing, it happens, swaps on the spare and he's on his way. Unloads the Jeep and brings the trailer back.
I go to park it in my yard and feel it clunk on the ball, It never clunks. I've had it 15 years, never heard it make any noise.
So I go to unhook it and the clamshell is open with the collar jammed against the back of it. He just jammed the collar latch down and pinned it. Somehow the safety chain is on top of the hitch, in front of the ball but under the trailer coupler. That thing went 1500 miles to Canada and back and drove all around town and never came off the ball.
