Just finished short trip with new truck....
All I can say is: wow. The new truck is a 2015 F350 6.7L Lariat 2WD DRW 3.73 Supercab automatic. The old truck was a 1999 F350 7.3L Lariat 2WD DRW 3.73 Supercab automatic. In other words identic...

It's a little early to claim mileage figures, but so far:
A trip of about 180 miles on the freeway I take frequently shows about 20 mpg empty (about the same as the '99 7.3L) unless there is a regen cycle in the middle of it, which knocks it to 18.5. That's on the meter, when calculated by hand both '99 and '15 seem to be about 1 mpg optimistic.
This is the first trip taken with the camper, the road over to the coast is 50 mph secondary highway with some traffic and stops, was just kissing 15 and then a regen happened, knocking it to 11.7. From there is slowly climbed back up, even though the coast road is hard on mileage. Got home at 13.7 on the meter but haven't filled it up yet. In the '99 I would get 14-15 indicated on that same trip.
But for the regens, it seems to be about the same as the '99. The regens seem to take 1 - 1.5 off the average. In a couple of months I will be driving to Lake Tahoe every couple of weeks, all freeway but from sea level over 7200 ft Donner Pass. I've done that maybe 50 times with the '99, it will be an interesting comparison. There are 13 grades on I80 which required the '99 to downshift to 3rd. I don't think they are going to be much of a problem in the '15!
Ford derates the chassis cab versions figuring that you are far more likely in those, to make continuous use of the power. My use is typical of this 1T pickup, camper and occasional towing or bed load. There is no reasonable (or legal) way I could use the 440 hp continuously. The engine has impressive complexity in sensors and powertrain control computers, and will not let you hurt it - if anything gets too hot or whatever, it derates itself. All the modern common rail diesels are that way I think. You can 'chip' them and wreck them very quickly, but that is a different thing. You could call the HP and torque ratings specsmanship, and it is, but the real useable power is still very impressive.
So far this truck is quieter, more comfortable, more powerful, and about the same mileage. The main downside of buying one is poverty. Also the smog controls are extensive and very expensive to repair I am told. Usually I don't buy the extended warrantee, but I think I may for this one.
