MPG for trucks with utility beds

[RVTRKN]

I am negotiating with my company to purchase a new 2014 4X2 2500 regular cab with a 8' utility bed, and was questioned about MPG for the CTD optioned power plant. I can't compare my 3500 (check sig) to a new truck. They will compare it to a similarly equipped Ford pickup, they like Fords, but it's not a accident that they own them with the 7.3.
I want to compare apples to apples so any input would be welcomed, the truck will probably weigh in @ 10K GVW, also, it will be the 3:42 rear end.

Well, I have a utility bed, but it's on a '10 5500 4 door 4x4 auto. Truck has 120K miles on it and has never gotten over 10 mpg. I know my setup is different than what you're looking at. But, since no one else has responded, I figured I'd throw it out there.

Thanks, my 3500 C&C gets around 15-17 MPG HWY at @ 10K GVW, but it's a different setup than the 2500, look at my signature. Also your rear diff is 4:88 I believe and is heavier in weight empty than my 3500 C&C.
