If what you will be winching are rollers then a Superwinch 4500 should be more than adequate and does not weigh a ton as some of the heavier units do.

There are pics of the installation of my Superwinch 4000s on the following link. It is not a recover type winch but if it rolls it will pull it up with little effort.
