23mpg! Lol. Maybe at 52mph flat level with a tail wind.
Don't blow smoke up the OPs u know what. He doesn't know anything about diesels and is liable to believe you!
I sold my brother my 06. 3:73, 2wd, 6 speed manual. I could repeatedly get 23 on highway (empty, doing 65). I would fill up, get on PA turnpike set cruise control at 65mph and head west, 100 miles later get off and fill up again, yes the 5.9 can really get that MPG. but only that kind of driving. back country roads or running over 65 and I would average around 17. put pickup camper on it and lucky to see 15, tow a 5th wheel lucky to see 13.
its all about how much air you are moving
Of course, and I can get my 4wd with mud tires to return over 21mpg on a flat straight road with the cruise at 55 but those aren't real world numbers for anyone unless that's all you do is hyper mile. It's misleading to someone who doesn't know much about these trucks and not a realistic expectation.
While I avg 17-18 mixed driving in my 07, the trip this weekend was more like 15-16 on the highway due to a little 4wd necessity, headwinds and several hundred miles with the cruise set to 80+mph.
To the OP, if given the choice and was not going to delete, I'd go with a def truck over the older dpf only rigs based on my fleet experience. I'd also go Ram and not just because I like them, but they had the least issues with emissions and overall when operated in horrible conditions.
