"I've owned all three makes, and recently too. I had an 05 Ford Powerjoke and a 06 Dodge with the 5.9 Cummins before I bought this truck, my third Duramax. This truck runs every bit as good as my last Duramax did with 2 chips, exhaust, and a AFE intake and filter on it. I can't believe how much power the new trucks have. It will run circles around either of the other two makes with or without a trailer! I pull heavy trailers all the time and there is never a lack of power. When I say heavy, my combined gross vehicle weight is always between 28,000 and 31,000 pounds. No, that is not a typo. You want the most power? Buy a Duramax."
"Duramax, Diesewl with Allison Transmission. Has Banks Engineering Chip installed which greatly increased the torque and horsepower. Permanent reusable air filter. Wash and reinstall. Increased exhaust to 4 inches with 5 inch tip."
"I have had my truck for over a year now and I love it. I can pull a trailer loaded down and set the cruse at 85 and it will never miss a lick. I have done a couple of upgrades my self that where easy to do with a noticeable power and fuel mileage gain."
