Thought that's what you were going for. As you see on mine I mounted a tool box. Inside is a 10000LB Ramsey winch.
If you add a small ATV winch to your headache rack you can use it to pull quads up among other things like deer, etc. The dove tail will be a good idea.
I'm adding an ATV winch to my rack so when I lift an animal, etc, I can use the little winch to pull it over the deck. Now I gotta swing them on which works but my little winch will work better.
