I am going to be buying a winch for my rig within the next few months. I really don't know much about them. I like the idea of mounting to receiver hitch (can winch from front or rear). I could also use it with my other pickup. I know there are many companies to choose from, Warn is local. Although price is always an issue. I don't want to buy this and regret not having bought a different one down the road. What size should I get, any specific options that are a necessity, etc.
