I just scaled my truck and trailer a couple weeks back. Fully loaded I was just under 26k so getting 10mpg calculated with no mods cant be too bad. Tried slowing down to 60mph and started getting 11. On my bare bones load getting 12 mpg at 60 mph . Cant wait to see what I get with I can put some mods on.

Default milage?

I've got a 2011 3500 duelly quad cab completely stock. After 10,000 miles the fuel economy is not at all what I had hoped for. I get 11 maybe around town and if I'm towing it drops off to 9 or lower. I'm open to sugestions if anyone has an idea to improve this. My 2007.5 got considerably better milage at 18 enpty and 12.5 towing.

I'm interested in knowing what you plan to do to your truck. I talked to a guy in texas last month while on vacation and he did a complete delete of the emission system with a programer and 5" exhaust but the figures he quoted to me for price of parts and fuel milage were hard for me to believe. Let me kow what you have planned and how it turns out.
