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.

I have the 7.3 with the 4.30. I am very happy with that combination.
Because I tow a fifth wheel, I have the long bed with the 48 gallon gas tank. It is a good combination.
I bought the 4x2 for two reasons. DW likes the ride with the IFS -- very important. Plus, with the 4x2 and the 7.3, we have about 1,200# more available payload than the f-250 with the diesel. While the 6.7 diesel is a great engine, the 7.3 with the 4.30 is a better option for us. About 2,000 rpm at 65 mph. You would not want to be lower in rpm because you are then lower on the HP and torque charts.
