Would you purchase a used hitch? Good or bad idea?

If you don't tell anyone they will never know.

I will go ahead and admit it. I knew this guy who was constantly swapping out stuff. he was not interested in selling his 15K Reese and told me that if i wanted it I needed to haul it off. Whoah, that was some years ago. Like previously said, it is just iron if it has not been damaged, what is the diff?
