Thanks for the numbers guys. I ran some numbers in a spreadsheet and the savings due to mileage won't pay for the diesel in any reasonable amount of time. But I also didn't factor resale (+for diesel) or maintenance (-for diesel).

I see all these number posted on the web (20mpg highway for example) but all my truck must be bad. They never come close.
My current 3.42 gear 2012 Cummins 12.5 around town 16 highway.
My 7.3 would get 10 if I was lucky around town.
My 8.1 got 6-7mpg towing.
9 around town in the winter.
You`d think just the aerodynamics of a dually never mind resistance of 2 more wheels would cost it in the MPG department. I`m not buying the same for both.

unladen meaning unloaded?
The diesels really shine highway unloaded , especially the pre emission ones.. 6 speed even better. Right now Diesel is cheaper than gas. Thats going to be short lived I`m sure.
Ive always wondered what the DRW takes away in MPG over a single. I think it`s at least 2mpg.

I`m still under warranty for another 2 years so it has to stay on.
I love the truck thou, so quiet, plenty of power, don`t have a single complaint except that I waited so long to buy one.
