hey all! quick question for anyone who has run with the benz 4000. How comparible are they to the s60 det. or C-15 cats? Looking at a 2000 western star with 72'' sleeper mbe4000 470 h.p. eng. w/13 o.d. trans and 3.93 ratio. is it a good combo. for hauling a 120,000 lb. load of pulp or not? just curious as to your opions. i an i a cat man myself and always have been but the price so far is right on this tractor @ $35,700.00 with all service and main. records w/ purchase. keep in mind any manufacturing problems with this series of engine are greatly appreciated. thanks for any input and happy holidays guys.
