Nissan Titan XD Cummins Diesel Fuel Mileage
Looks like the Titan/cummins/aisin setup falls short on the fuel economy both unloaded and loaded. Not sure if this run included a regen, but I'm really surprised how poor the unloaded fuel economy is...

For a little different perspective on fuel economy my DP with a Cummins averaged 11mpg on a 4,500 mile trip from Tennessee to Glacier NP and Yellowstone. This is on a 24,000lb vehicle that is 8 1/2ft wide and 11'4" tall. I don't think that my daughter's ecoboost has ever gotten below 18mpg w/o trailer and as high as 27. So yes, I find 17mpg in a pickup to be unacceptable, especially if you have to factor in the extra cost of diesel fuel and exhaust fluid.
By the way, the latest issue of Car and Driver (February) has their test of the diesel and they observed only 15mpg. I am sure that they drove aggressively and that I would get somewhat better but that is still low.
