Dually gearing? Coming from a SRW
Sold my 2005 F250 Powerstroke diesel SRW, 3.73 with 285s on it (34s). Gearing felt great, at 2k RPM I was around 74 mph. This new dually (same year/engine) has 4.10s and 245s (like 31-32 inches). ...

My new F350 Dually gave me 10.5mpg on a 1200 mile round trip with the latter half trucking along at 70MPH the vast majority of the time and it has 4.10's. I'm guessing the 6 speed gear box is the reason and perhaps the massive power (hard to imagine it until I drove it fully loaded for a week long trip).
My 6.4 with 3.55's in comparison only gave me 9mpg in those conditions on the same trip.
