I've always been keeping an eye out for a winch and through a buddy found a guy parting out an old towtruck. The winch is an electric warn winch, seems fairly big but couldn't find a rating. AT first i figured was probably pretty weak as all it needed to do was lift the front of a small car off the ground, then I figured it's probably also used to pull vehicles out of ditches and such.

Any ideas on what a tow truck winch is rated at? It's the kind where the winch is mounted behind the cab and the cable runs over the boom.
Just a small pickup based rig kinda like this but don't think it was a dodge http://www.vehicle-liquidation.com/showroom/images/DODGE%20TOW%20TRUCK%201.jpg
