Gear ratio advice 3:73 or 4:30 on Super Duty
I am in the beginning stages of looking for a new TV and was looking at the Fords to start off with. (Dont worry Dodge fans I will look at them next) I see that Ford has either the 3:73 or 4:30 gears ...

I have a 2016 f350 dually 6.7 with the heavy tow and 4:30 gears. the only other choice in dually is 3:73, while im sure it would be a little better on fuel I am getting 15.6mpg empty on the highway at 68mph.
My previous 2011 f250 with the 6.7 and 3:55 was getting just over 17mpg on the last tank, truck had 108k miles.
The way my truck came it is rated to tow 26k lbs, I believe the 3:73 was rated for 23k lbs.
Btw...this truck is my daily driver and I have no regrets with the gearing, I may pay a few more dollars at the pump but has had zero hesitation towing. Also I bought this truck because it was on the lot, if I were to order one it would have the 3:73 gearing just because my 15k lb trailer doesn't need what I have.
