If you're just looking for tool that will give you pull you out of a place where you cannot get traction, there some winches that could help you even if they were just receiver mounted. If you expect the winch to pull you out of a ditch or mud hole, you will have trouble finding a winch with the capacity you need and creating a mounting point that is strong enough to use without causing more damage.
I have a cheap brand high weight rated winch with two pulley blocks that mounts to my receiver. I have not had to use it for my own recovery, but it has dragged 12K lbs across dry pavement with all four wheels locked using double line pull. I expect my winch will last me a while since it is used infrequently, stored indoors and used at half its work load rating.
