This.
Without any diagnostic codes being thrown the mechanics are not going to have a clue what's wrong or how to fix it.

The DPF is for catching particulates, formed when combustion temps are relatively low. Empty driving, especially in town and in cold weather, will never raise the combustion temps enough for a full burn, hence the DPF has to work extra hard.
DEF is used to react with Nitrous Oxides, which are formed under high combustion temps. You want to keep your truck running at these higher temps, because 1) It's more efficient and 2) It's easier to add more DEF than it is to clear soot out of the DPF.
So again.... Drive it good and hard to get it cleared up initially. And then try to change your driving cycle. I'm guessing you must do lots of short trips or idling now. You might come out way ahead in fuel $ and future maintenance headaches if you picked up a smaller car for in-town use.
