Do I need a hitch lock?

My trailer is 20 yr old so I doubt if anyone but me would want it, so for me a lock is not needed, plus I leave my hitch hanging from the king pin when I am parked for extended periods.

I guess someone with rails in their truck that match my hitch could take my hitch and trailer if they were willing to spend the time, but they would have to really, really, want an old 5er :)

I use a kingpin lock when our fifth wheel is at the storage lot where we keep our trailer between trips. While I don't think it's necessary, it's still cheap insurance.

I use a lock when I'm hitched up, just so someone can't pull the handle and I drive out from under it without knowing. But I've never tried using a lock to keep someone from stealing the trailer.

I bought one but haven't used it. I guess it depends on where you are camping. If I was camping close to a big urban area, I might be more inclined to use it. But like you say, I think a break in is more likely than stealing the trailer. If I stored my trailer at a storage lot, I would definately use it then.
