I just installed a spare hoist under my equipment trailer. It worked out perfectly. I went with the same one that's under my F350. Nice and heavy duty. I checked out the a/m offshore cheap ones and they are... The factory Ford one is much more solid. Here's a few pics of what I did. Nothing fancy. It just works. For the rod to lower it you can either use the factory Ford rod or a 3/8" drive extension.
