I bought my truck brand new and I absolutely love it. Pulls great and hauls anything that will fit in the bed. I forgot about girls for about a week when I first got this truck its that good.
6.0 Liter motor has awesome power. My Dad's company has 8 Heavy Duties and some have 8.1 liters and other the 6.6 Duramax but the 6.0 Liter has great power and torque for anything that I tow. I tow a 973 bobcat and kronkite trailer combined weight of about 10,000lbs and it pulls it no problem
With the 4.10:1 rear-end the truck will only cruise about 70mph but the truck isn't for the average person it's a working truck that's designed to pull
