05 Cummins Laramie. 30K Miles and 10K worth of repair bills. Nice looking truck and it holds the pavement down in front of my house nicely. Lots of power, decent mileage for what it is, fairly comfy on long hauls. Injectors are delicate which can lead to major engine damage. Poor factory fuel and air filtration. Weak trans. Lots of creaks(sliding glass) and rattles(rear storage) and wind noise(drivers door). Radio dash knob doesn't work. Abysmal customer service. If you are considering a used one get a Manometer test done first.
Torque, Heated Seats, Sound System.
A lot. Better fit and finish, better filters. A company and dealerships that even attempt some level of customer service
