My dentist just picked up a 2013 or 2014 f350 diesel, he said the one thing he really liked about it over the dodge and chevy is that he didn't notice as much turbo lag. Said it got into the boost the quickest and had the power right away. Those King ranches are nice inside. I think towing my blazer down to moab and back I got around 9-11mpg, I think I had the cruise set at 70mph, but I took it to 75 a lot also. Might not get the mpg that a typical cummins owner says he gets (like jeeper said) but I love my truck.
