Rule of thumb that I've heard is 2.5x your vehicle weight minimum. I'm running a Mile Marker 9000 lb electric winch on the front of my Sammy. 4wheelparts.com has weekend sales where they sell that winch, a tow strap, 2 tow hooks, a cheapo watch and a video for $499.00 with no shipping. Just check in every Saturday or so on their website, or sign up for their web sale alerts.
