Doing all the "what-if's" can drive one crazy. When we test drove the 1500 hemi-testing ride, etc., wife said, "Why not this one? Why do you want the diesel?" So those "what-if's" come back and after looking at the Hemi's 17mph--heck, I might as well jump to a 2500 Cummins. They get about the same or better fuel economy. Only problem---I don't need that much truck anymore. But then again...(dang it...doing it again!)
