this is the mac daddy in the Dodge truck world, this was built for only 2 months then they went to the 24 valve motors and they have issues. what makes it very rare is its a quad cab with the bullet proof 12v motor.
'98, Dodge 5.9L 12 valve Cummins, AT, Quad cab, these knock down 18/19 around town and 20's working and will get 25 unloaded on the highway,and ride smooth as a caddy. and will pull anything you hook to them.
