Lost a pin on the tow bar. Don't use these pins!!

After many years of towing with a tow bar, I noticed that the pins would always move in one direction. Because of that I always insert my pins from the inside to the outside so that the keeper for the pin is on the outside. I know some will say that it does not matter which direction you put the pins in but I have found out differently. In any case, by installing the pins this way, it puts no pressure on the locking pin. Pin install example
