I just drilled a 1/4 inch hole in one of the base pins and then pad lock it. If they want it bad enough they will get it. I also drilled the latch handle and put a hitch pin in it so I can remove it. I really dont think it's much of an issue though.
When I unhook at the campground, I just take the head off and put it in the basement. I lock the base to the tie down loops, but that would just stop the lazy thieves.
IMO if someone is ambitious enough to steal a heavy, awkward, not exactly easy to pawn item, then I don't think a couple of padlocks are going to slow them down in the slightest. Doesn't really seem like a spur-of-the-moment theft. There are battery powered abrasive wheel cutters that will go through a padlock like a knife through butter.
I have a valley removable hitch. pull 4 pins and it's out.
I drilled the hole in one of the pins a little larger and put a small lock on it. Sure they can cut the lock but it's a deterent. you can also buy hitch pins with locks.

Looks like you could just loosen the top bolt on the square post pull the pin and lift the whole thing out and be on your way with it. What has anyone done to keep their's from being stolen?
I have an NRA sticker on my truck.
