This is a great truck. Lots of power, very dependable, and very good design. This is my first truck and I love it. I have dual exhaust on the 5.3 and it sounds great. If the gas pedal is pushed a little hard you won't get good gas mileage but I keep it under 2000 rpms and and get a little under 20 mpg.
This truck does need a better stereo. Other than that it's great
