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.

We are Ford folks..Blue Oval all the way. Could afford a new 6.7 diesel, but there are a lot of new hidden maintenance costs that go along with all new 2020 diesels.
I would not say the diesel maintenance costs are "hidden", unless, like you, you have an older diesel that does NOT require DEF !

Just thinking our next truck might be the new Ford F-250 with the 7.3 gas engine. But the reported terrible MPG towing gives me a lot of pause.
Real world towing and around town mileage from 7.3 gas owners would be appreciated. Perhaps there has been improvement in the 2021 models?
I would not condemn the gas 7.3L just yet. Give it a full year and keeping looking for feedback !
Ford put a lot of money into that engine (and the 10R140 transmission) in order to replace the old V10. They had two goals for a gasoline engine : more power and better fuel economy than the V10. With the 4.30 rear axle, it will pull a ton, but that will hurt fuel economy.
Check the fuel tank size !
