Duramax vs. Cummins- Need some feedback

Alan Roehrich · 12-19-2008, 09:50 AM

We've had great luck with the Duramax powered trucks. Excellent mileage and power, and good reliability. So far, in our group, that's about a dozen of them, and only one gave any real trouble. It was not all the fault of the truck. It was already long out of warranty, the aftermarket shop screwed it up badly, and it took the dealer 3 tries to fix it. From my experience with the Dodge and the Cummins, you get either mileage or power, but not both. If you get one with a 3.55 or 3.73 gear, they get decent mileage, but don't run that well. If you get one with a 4.11, it runs good, but the mileage is nothing to brag about. And the BullyDog stuff makes the Duramax get better mileage and more power.
