I just cannot stand the DPF technology on the new diesels. Some day soon I think they'll have it figured out to where it will just use SCR and tuning. The regen process is stupid, and a very clumsy band-aid. I don't like the idea of going into limp mode when I am out on a slow dirt road somewhere, or catching the cheat grass on fire because my 1200+ degree exhaust came into contact with it.

By dpf I assume you mean def technology. I was a little concerned about how often I might have to add def, but after putting about 6600 miles( about 3000 in Colorado) the def is almost a non issue. Most truck stops have def for less than $3.00 a gallon
At the pump. Every Walmart and auto parts store has it in stock.

I carried five gallons with me on my Colorado trip because most of our travels were in pretty remote areas. Brought most of that home with me. I ammnot sure how much my truck has consumed but it has not been much. I am guessing but I have probably used around 10 gallons and probably 2/3 of that was towing.

No, I am talking about the DPF (Diesel Particulate Filter). I have no problems with the DEF (Diesel Exhaust Fluid) which is part of the SCR (Selective Catalyst Reduction) to reduce nitrogen oxides (NOx).

The diesel particulate filter (DPF) is a crude technology which physically captures soot, then after quickly filling up, burns it off with diesel fuel at extremely high temperatures (regeneration). It is basically an on-board incinerator in the exhaust system. Lowbrow technology, and a band-aid to take care of the soot problem. It is a system used with all diesels since 2007.5. The SCR is a system which has been used since 2010 (2013 for Ram because they had credits) which reduced the NOx and the number of regen cycles needed, but still does not eliminate them.
