My 06 has 182K on it right now. I bought it with 126K 4-5 yrs ago. I change the oil 4 times a year and that's about it. I used a programer to get a little more bang from it as the 06 4.7 is a dog. With the extra power the programer added, I'm happy. Decent power now and very decent MPG. Even living where we live I get 16.5-17. On a trip to the Mopar Nats I got just under 20. 2006 1500, QC 4x4, 4.7/auto I did have to have my trans rebuilt around 150-160k, that was about 2 grand. I'm a 4.7 fan.
