Towing capacity for the Ram is 9,200lbs
The mileage difference between 3.55 and 3.92 is insignificant.So, unless a buyer goes with the 3.92 ratio or a 4x2 regular cab, they are limited to about 7k. Of course the 3.92 ratio will cause a drop in mpg. I still think the 5.0 would have been the better choice overall, and I know the Nissan will tow more (2-3k more) comparably equipped, and likely with an insignificant mileage hit. Only time will tell.....
