I have a 14 ram cummins 3500 dually, I bought the truck for the sole purpose of never wondering if I'll have enough, can pull what ever I throw at it. Open road I get 26mpg and mines not even broken in yet just at 57000 miles. Def does suck, but its biting those who wanted it in the butt since it's not the money maker they thought it was going to be, been biting them since 06 1/2 rams when the first 6.7 came out. Each do have their advantages, I even drive .one every day it's my daily. Maintenance isn't that bad really, but you cant really beat the torque of a diesel. Just my .02
