Only have 800 on mine bought it with 600. I seen one at a guys house that was selling them close to me. Thought how kook would it be. Always wanted one and found a guy that traded me my dodge diesel 1996 cummins with a built auto tranny. He was from Missouri. Drove my truck down with my Durango on a trailer. Picked it up and drove home. Been fun and some work. But all in all pretty good machine.
