Has anyone ever seen a 12 volt capstan winch. It's the kind of winch you see on ships and kind of looks like an hour glass. I have two bum shoulders and cant do long drags. My thought is to build a capstan winch that I can put into my hitch receiver then connect it to my trailer light socket. Turn on you parking lights and you have power. A capstan winch has the advantage in that you can use any and all the rope you wasn't and can tie tropes together without a problem.
