I've got an 04.5 with an automatic. It's got 197,000 miles and most of that was pulling a car trailer. It is by far the best truck I have ever owned and I'm not afraid of the automatic even though I've heard the stories. I know another 06 with an automatic that pulled a two car trailer professionally that lasted almost 300,000 miles. My only issue with this truck is the cost of the injectors. They are crazy expensive compared to earlier models. I'll stick to the 03-up trucks for comfort, braking, power, and generally low maintenance.
