I've had 5 Durango's from 99-02. My currant one is a 01 R/T. I like them, easy to work on, ride nice, not to big or to small. The 4.7 has a bad rap. I never had any trouble with the 2 I had. The key with the 4.7 is maintenance, got to keep the oil changed and use good oil and they can't get hot. I dropped a 408 in my R/T. Mileage isn't bad, about 25 on the hwy. I've broke several posi's, the factory uses super cheap ones.
