Back in 1995 I sold a 1 year old Dodge 2500 4x4 regular cab Cummins to a friend of mine. At the time it had about 15k miles on it. He still has it today with 300+k on it. He has replaced virtually everything on it at one time or another over the years,.. Except the motor,frame and axles. It has always been a daily driver and never really worked real hard.
