Newer 6.7 power strokes are simply NOT getting as good of mileage as your lesser smogged 6.0.
From what I have gathered 6.7 due to smog equipment and regen cycles you can expect at the most 11 mpg while towing and if lucky 14-15 empty.. Heck my 2013 with 6.2 is getting me 15.5 empty highway and towing 7K I get 9-10.1 MPG. The days of diesels getting 19-20 empty and 14-15 towing are gone.
Not to mention the newer diesels have a lot of interesting quirks like FORCED 50 MPH speed or even worse immediate SHUT DOWN on emissions faults :E which can happen at anytime without warnings even while towing... I certainly would not be happy about having my truck randomly decide to stop in the middle of towing at 70 MPH :S
I just gotta wonder where some people come up with this garbage? My 6.7 Ford pulls 14,000 at 12.2 MPG. And gets 16.8 MPG Highway not towing. Regen's are NOT a problem. Interesting quirks? Not here.
Everyone has a right to their opinion. I guess. But that post is simply not fact. That is as kind as I can say it.
Oh...on edit...I almost did experience an interesting quirk one time. The control center told me my DEF was going to run out in 500 miles. You use more DEF when towing. I refilled it at 150 miles left to go. If I hadn't done that, the truck would have gone into 'limp' mode when it ran out of DEF. Quirk avoided.
