Loaned my Ram 1500 to a relative the other day and upon return the insert from the hitch was in the bed but the pin was missing. I had a pin with a hole that a clip key slid into. I was pretty sure ...
Never had a shank disappear off my truck or had anyone mess with one. I don't often leave the shank in the receiver because they tend to rust in place after a few weeks, though.
I have been inconvenienced by a locking pin not wanting to unlock on multiple occasions. Had to get out the death wheel.
