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.
