Can't answer that question and don't really care what Ram puts into the half ton pickups. Half ton won't do what I need to do. Again, not going to knock Mercedes diesels, never owned one but, I am a Cummins fan. Don't care what they put the motor into. I am not necessarily a Dodge or Ram person. But, if it's a got a Cummins, then I know it's going to be reliable and competitively fuel efficient with the power and torque I need. But, I will say that regardless of what engine or brand a person likes, never buy the first year of anything just out on the market. They all have bugs that haven't been totally worked out until the second or in some cases the third year. I've been a loyal Cummins fan for 30+ years and well over a million miles. Getting me to change to a MB engine won't be easy. Not impossible but it won't be easy.
