If you can find a low mileage 2007 LBZ Dmax I'd get it. They did not have the DPF but they did have a cat and the EGR. I had one and loved it wish I still had it. I currently have a 2012 F-250 with the 6.7 which so far I like it a lot.
The Dodge around that year range are good. I have some friends that have them and they like them. They are die hard cummings guys but they claim their mileage is on par with the PowerStroke and the Dmax. Mileage number range from 9-14 loaded and 15-19-21 unloaded depending on the right foot factor.Ofcourse these are stock trucks.
The maintenance cost vary from truck to truck. Example the PowerStroke holds more oil than the Dmax and has 2 fuel filters. Overall theres not much difference between the Dmax I had and the new Ford. The DEF is an added cost but I new what I was buying.
