Well....I already have a Ram 3500 cab/chassis with the 6.7L diesel. And I have a Ram 2500 with the 6.4L hemi. This truck is not to replace either of those. It is an additional truck to my fleet. I use the 3500 to pull heavy loads with a 28' gooseneck and we use the 2500 to pull lighter loads with a 20' bumper pull trailer. But I can, and have, used either one to pull either trailer.
This new truck will mostly be used as my personal truck, but still can be used to pull either trailer. I consider this new truck as my reward for 20 years of hard work building my business to where it is now, and I can now afford it.
And, in my opinion, there is very little difference in cost of ownership between a diesel and a gasser. I feel that for pulling heavier loads, the diesel is the better option, but for lighter loads, a gasser works well. As I mentioned in my first post, I already have the 6.4L hemi and I really like the way it handles, and that's the main reason I've order the 6.4 in this truck.
