104,000 km (abt 65k miles) although I have only put 6000km of that on it since I bought it in Sept. I can hardly wait till June as we are going to take it to Tennessee hauling our 34 1/2ft travel trailer and the wifes sister and hubby. So I will have about a 4000 mile real world towing test.
45000 on my 12. My trailer brake controller also went bad, I would be driving down the road with no trailer hit a bump and get a message " trailer disconnected " then next bump " trailer connected". Other than that I havn't done anything else.
19800 bought it last week of July. I'm getting the "Trailer Disconnected" message but haven't taken it back yet. I also have a small rust spot starting on my passengers side door. I'm going to take a pic and start a separate post about it. Other then that I LOVE this truck!
I got 21500 on mine. Got it Feb, 18, 2011. Have not been to the dealer for anything and only added extra things to mine. I love the truck and has done everything I asked of it. I just sent in a sample of my oil to see how it's holding up after 20,000 miles.
