Hello all, Doing some research on Class 8s, was curious which engine is the preferred motor to have here and why. Not owning a semi before and owning a handful of dodge and ford diesel trucks in my life, I am naturally allured towards the Cummins trucks, just curious what else out there is considered a good reliable engine, I'm mostly looking at moderate mile used trucks, as I don't want to spend a lot of money on a newer truck at the moment. I did talk to a guy named Rawles on the facebook group and he swears by the Cummins, but when I checked out his youtube channel he only works on and owns Cummins, so guessing a bit of a fanboy.
