Ford F-250 7.3 Gas Engine Axle Ratios
Is there much difference in towing milage, and around town/highway mileage with the new F-250 7.3 gas engine with rear gear options? Considering 3.55 or 4.30 axles ratios. Any input is helpful.

The only transmission available is the new 10R140.
The 4.30 would be great for pulling stumps or towing over 10,000 lbs, but the fuel economy would not be very good. It depends if they can program the transmission to start in 3rd or even 4th with a light load (driver only).
Personally, I would go with the 3.73 and electronic locking differential.
