No personal experience but do know that some of the earlier models of this engine had trouble with the block cracking. I think these were late 90's and early 00's. Most cats are good motors but be prepared to shell some money out when you do have trouble. We run 2 kenworth's with cats and have had little trouble but when we do they have to go to the dealer because you have to have special tools to work on them in most cases. All of our logging equipment has cummins motors in them and they are much easier to maintain and work on in my opinion. I would try to find something with a cummins motor if it were me. Just my preference though. Good luck.
