hey everyone I am looking to buy my first diesel Ram, my father has a 95 2500 with the 5.9L Turbo Cummins Diesel and it has over 300K miles and runs like a tank.
looking into newer truck I have come across the ECO Diesel on the 1500, are these as good as the Cummins? I know the Cummins is bigger and has more power but all I tow is a 15 foot U-Haul trailer so a 2500 Cummins is more truck than I really need, but I want a truck that will last over 200K miles that I can drive for years and years.

all suggestions and advice will be well appreciated.
