Hi NC,

I have a 02 F350, DRW, CC, lwb, 6spd, 3:73, 4wd and pull a RV, about 16kGCW, and get 14.1mpg pulling the Colorado Rockies and 16.5mpg pulling the AZ mountains. My 15k mile lifetime average 17.1mpg that includes 6k miles of pulling 16kGCW. All hand calculated, not the overhead puter. That's pulling 60mph on the flats and 42mph on the 7% & 8% grades.

From what I've seen of the new DBW (drive by wire) fuel systems, it's all in how you drive them. A tad to hard upon acceleration drops mileage considerable.

I pull by maximum torque rpm or 1600rpm at all times. I shift at 1250rpm on level ground and add fuel slowly to reach speed. That's to keep from lugging the engine.

I just got back from buying a couple tractors and that ran me upto 31kGCW for the 2k mile trip home. I didn't like the fuel mileage as it dropped me too 8mpg while using turbo power at 2250rpm. Although I could pull the load at 1600rpm and 10.4mpg, it was just so darn slow so it was worth the 2mpg loss just to get home sooner.
