Welcome! It could very well stop up the DPF if the system isn't regening correctly.. it's a gamble really. But if the dealer is covering the issue perhaps just ride it out. I wouldn't take a road trip though.. :)
Hey @jrizzil
Perhaps this gentlemen can provide more information for you?

Just drive enough interstate (IE over ~50 MPH) for a decent distance to allow the truck to regen properly would be the only catch if you're use to a gas engine.
Welcome @Chiefwahoo !
Glad to have you here. Diesels are fun.. just take care of it and it should take care of you. Start reading around on the forums here, plenty of info to go around!
