This is a great truck in every way - except the rough ride. I love the accessories and the 5.7 liter engine. The six speed transmission is very versatile. The 4X4 works great in heavy snow and on ice. The ride, however, is bone jarring and very uncomfortable on anything except a smooth asphalt hiway. It feels like it needs about 2000 lbs. of load in the back to calm the jerky ride. I strongly recommend that if you have neck or back problems, look elsewhere. Fuel economy is not great but is what I expected - about 15 mpg average for all driving conditions. Brakes are excellent, leather seats also.
5.7 liter engine has loads of power. Interior is excellent. Good sound system, navigation system is great. Tons of leg room front and back. Very good towing capacity and handling. Turning radius is incredibly small for a big truck so it is easy to park.
Do something about the rough ride! Fix the gas gauge, which reads empty with six gallons in the tank. Sonar back up warning goes off six feet from an obstacle so it's not much help.
