Changing differential gears
WWould like to hear from those that have actually changed their rear-end ratios. Did you get any improvement? Was it worth it? Any pitfalls?

I understand what your saying and I believe Ram's specs but if you talk to people who have gone from 3.42 SRW's and moved up to a dually with 4.10's, the driving experience is vastly improved even when not loaded. When loaded they're able to get off the line much better which is always a sore point with diesels. I'm hoping the fifth gens have an 8 speed trans to make the 3.42's more palatable (doubtful).
Of course that will do better off the line towing heavy, you are looking at 20% more torque going to the wheels with that change assuming everything else is unchanged.
Define "driving experience". If you are willing to give up some MPG, it will be faster accelerating running empty but really, modern diesel trucks are not hurting for power running empty. They have plenty good acceleration. But most people would prefer a couple extra MPG if they do any significant driving not towing.
