The point most of you seem to miss is that if you actually have to sell the truck to Americans willing to pay real money, as in $30k or more, its not going to happen with a 4 banger full size pickup, I don't care how much torque it produces. Besides if Chrysler/Fiat wanted a 4 banger they would use their own 3.0L from the Promaster van which is being sold in the US. No need to run off to Cummins.
