McDonald's is the best selling burger, doesn't mean it's the best. What about the transmission? The Aisin is a great transmission, I have 67k on mine and plow snow without a hiccup. They all do. They all have for many years. What's your point? Ford owns Ford, it's all in Ford's hands. The fact is that the inline 6 diesel makes greater torque at lower RPM than a V8 will ever be able to do, because of it's design. And when you want towing or plowing power, you're talking torque, not HP. And higher torque at lower RPM's means better fuel economy and less wear and tear.
