Great report, thanks. Mileage is definitely better than my 06 350 CC dually diesel, and will probably improve with time. I don't think 3.73 was a 1 ton option in 06 though? At least that's what I recall at the time...I've got 4.10's.
What size tires came on the truck?
The towing chart in the Ford Diesel Supplement shows only the 3.73 for the SRW diesel 1 ton. I have a 2006 F-350 SRW, and it is indeed a 3.73 limited slip, according to the differential code on the door sticker. It turns around 2000 RPM at 70 MPH on stock 265/75-17 tires.
