I got a lot of cars moved with the little 2500 harbor fright (on purpose!) winch, but there were lots of times I wish I had more.. Bought a 9 ton HF, acts like it could pull down a house. Battery and winch in a box, on the trailer.
I got my old 2500 bolted to a mount to go in a receiver, but set up to be chained to a tree, or whatever. Handy for moving cars on those wheeled rollers.
Edit: beautiful family, and family of cats!
