The guy I know was getting 35 highway mpg with his mega cab plus it was chipped, bigger tires, etc...... Who needs 1200 hourse for in town driving, who needs a 2wd, for that price I would just get 4wd and be done with it. Forgot to say the manual trannies are fine but the autos in dodges are junk. How much was sank into building a 1200 horse cummins. I loves cummins to, sad to see the factory that was in my state closed down due to the american economy taking a plung. But i do live 5 minutes from a CAT (catipilar) plant, love it when they fire up an engine, huge clouds of black smoke. If I do have to do another engine swap, a diesel is going in next, no if, ands, or buts about it.
