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...

The F450 will be able to hold 6th with the heavy load in tow, while the F350 will be in 5th gear most of the time.
The F350 DRW does tend to have a better payload than the F450, when otherwise comparing apples to apples.
Actually, I haven't seen this. I can set the cruise at 70 mph and it rarely ever leaves 6th. Makes traveling nice. In all honesty, my 2011 F450 and my 2015 F350 tow just about the same.
