That's assuming the 6.7 is an upgrade from the 6.8.
I can only speak for pickup trucks, but it's a huge difference. You are talking double the torque from 400 to 800 ft lbs. It would pull grades much smoother and would be able to handle a much larger towing capacity. Of course the Tranny would have to match but again, they do that in trucks every day. Gas motors have come a long way for sure and from what I read they get the job done for the most part, but my experience is you can't compare them to a modern diesel when it comes to torque and pulling power (exactly what a MH needs).
