new factory transmission less then 10,000 miles ago. Clean truck with lots of work left in its lifetime. This truck was used fro recreation and pulling a 5th wheel. It has some miles but not many for the legendary Cummings engine. With the new transmission on this work horse i don't see it lasting long. If your in the market for a used diesel move this to the top of the list and come see it in Ashland today. It has a L6, 5.9L; Turbo high output engine.
