Difference between 4.30 & 3.55 gears
My 2011 F-350 has a 3.55 geared rear end. The new 2017 F-450 only comes with a 4.30 geared rear end. Basically the same engine (6.7 turbo diesel). Does that mean better or worse fuel consumption...

May I inquire what you're pulling?
Yes you may:
2014 Bighorn 15800#
and
2016 Palomino T/C with loaded weight of 3950# (which includes tongue weight of 10' utility trailer and Super Truss Hitch system)
Hope this answers your questions.
Also, to all who have responded, many thanks. I was told by Ford salesman that the higher the number on rear end gears, the better the fuel mileage. I tend NOT to believe everything I am told, thus the question for those with actual over the highway experience.

Why are you considering an F450? In my mind the F250; F350 and f450 are all basically the same truck. The f250 should be discontinued as it has nothing to offer. The f450 has 4.30 gears because it is designed for towing 25000 to 32000 lbs. The truck designed for your trailer is the F350. I take it you want dual wheels? According to Fords build and price on their website, the gear ratios available in the dually are 3.55 and 4.10. unless your towing extremely heavy or spending much time off road the 3.55 gears will be better suited and give better fuel economy especially when not loaded.
To answer your question, Why F-450, I have always been guilty of, "If big is good, bigger is better".
So maybe the F-350 is the better choice here. Thanks for your input.
