Building a hitch winch to drag a 330xi onto on trailer

I built a winch plate that attaches to my hitch in order to drag cars and tractors onto a trailer. Because I do not currently have a trailer of my own, I built the winch into my hitch so I can use it with any rental trailer. The 5k winch will have plenty of power to pull any vehicle these little trailers can handle, if not I can use the snatch block to increase my pulling capability. This winch worked out very well and its so compact I can still drop my tailgate!
