I am in a similar quandry. See my post in general discussion. I do show the 4.7 at 4650 max weight in what I've got. The best Durango/Dakota is the 5.9 2wd, its rated at 7550. All the 5.9's I find are plain jane. It seems a bunch were ordered for fleet duty and are now coming off lease. THe only trailer tow 5.9's or 4.7's I have been able to find have been 4wd, or awd.
