Fuel Mileage
I have a 08 F-350 4 Wheel drive and the best mileage i can get at 65 mph without towing anything is 12 MPG and towing a 5 th wheel 9 is the best I get. Have I got a lemon or are they just getting crappy mileage ?

So it is a DRW, with low mileage on the odometer. Your MPG is similar to what others are getting with a DRW 4WD. Mileage will get a litttle better as the engine breaks in.
DRW, 4WD and low gears drop the mileage, then when couple with the EPA mandated emissions requirments (EGR, DPF etc) mileage drops some more. The Emissions requirements of the new diesel engines has dropped MPG about 1-2 MPG on the 6.0 compared to the 6.0.
Also for best MPG keep your RPM at or below 2k. If you routinely cruise above 2k your mileage will drop substantially.
What is your GCW when fully loaded?

There are so many posts of "poor mileage" with the 6.4L that I don't think it's "poor mileage". I think it's "standard", "regular", "normal", "stock" mileage. 12mpg isn't that bad with that set up, as I've read a number of 6.4L threads and getting better than that is what's abnormal. You have perfectly normal mileage, perfectly average mileage. Not to be too brash, but to complain about that would be to complain about buying an apple and having it taste like apples, or buying a 6.4L and finding it's only 6.4 liters. You bought a 12 mpg truck, plain and very simple. The problem is people talk about diesels getting "great" mileage, and in today's trucks they don't. With ULSD, emissions, and whatever else, they don't get much better than what you've got. Lesson though, tell others what you have and what kind of mileage you get. That's at least going to save the next person from mpg shock.

Sort of interesting though. My V10 gets 11 mpg in "suburban" driving during non-winter. My passing thought is that as diesels begin having to meet the same emissions standards as the gassers, their mpg advantage is diminishing.
