I have the truck at a 3rd party shop right now they are looking over some things on it. Isn't the DOC/DPF the same thing?

The DOC (Diesel Oxidation Catalyst) is first in line, it uses the exhaust heat and fuel from the aftertreatment injector reacting with the media it's made of to create the 1100deg heart to burn and ash off the DPF. This media can be "washed out" Prematurely by excessive regen, Blowby (oil) or coolant from an upstream failure. The DPF is a trap filter that can be "blown out" pulse cleaned, good, or "baked" better. Neither will last forever and you are inside the replacement window. Please let us know what they find.

One thing I can't get to anymore is the Cummins claim history. Ask the dealer if they can get it (they can if they really wanted to) or your local distributor if they are feeling particularly helpful.
