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.

Bought my 7.3 gas strictly for towing our 30 ft trailer and the 3.55 gears doesn't acknowledge a trailer is in tow.
4.30, 3.73, 3.55....10spd makes them feel the same.
Tremor sitting on 35" tires, maybe 4.30 is justified. Imo
But how do you know different gears won't make a difference towing your trailer?
It would be marginal towing at only half the trucks capacity.
Exactly! But if towing more weight that’s when the deeper gears make a difference!
