Nope they dont put the Cummin's in the 1500 only the 2500 and larger...If you can get a good deal or at least what you think is a good deal , Buy the stinkin thing..As long as it will do what you want .
TTCLM is right about the Cummin's though , they run almost forever and will pull a frieght train. If ya want to go fast get one with a Hemi , but you will need to have plenty of gas cards handy.
