I have 61k miles on my 2009 Hemi. Since I have owned it I have made 5 cross country trips each totaling about 6,500 miles. So much of the time, 50% it has been running 10 to 12 hour days between 65 and 80 mph, usually run four days out four days back.
Engine runs flawless no problems from the drive train, except a leaky pinion seal at 42k miles. Shifts are fast and smooth. I did tow a car out to Tennessee on one trip and total weight was just over 6k lbs. No problems at all and a comfortable tow.
The truck is on the Chrysler maintenance plan and I follow it faithfully. So all fluids are changed a little earlier than most people would follow. Truck is bone stock performance wise.
This truck is just fantastic.
