My next one will be a gasser. Im not towing as much as I used to and diesel emissions are crazy, though I haven't had a problem, yet. From what I'm seeing guys with the new 7.3 are getting 12ish mpg mixed city hwy driving. I get 16 with the 6.7, not even figuring maintenance, just the price difference between gas and diesel around here it's basically a wash or pennies cheaper to drive a gasser. And the new 7.3 is more hp but a little less tq than the old 6.0 diesel that used to pull my stuff just fine. But hopefully that'll be 10 years or more down the road.
