ELKiller: I bought my first Dodge and my first diesel 4x4 pickup truck NEW back in 1996. That truck has served me exceptionally well, been exceptionally dependable and gotten good mileage since day one.
I have 140,000 miles on it now and it now sits in my warm garage year round until I need it to go Hunting or fishing.
Never a wrench has been touched to that engine or its components.
It IS the 12 (twelve) valve model and with 5 speed manual transmission and puttering along I get 21 -22 miles to the gallon.
IF.... and that is a mighty big IF, you can find someone willing to sell their 1996 to 1998 Dodge Cummins extended cab diesel 4x4 with 5 speed transmission I highly recommend it!
I am hopeful this truck/engine lasts me the rest of my life.
Power, dependability and somewhat good mileage - if you find one - buy it.
Hold into the wind
