Just a quick update from our previous saga of the DPF lamp causing a shutdown: we’ve driven 2000 miles since the “fix” (the fix being removing a piece of paper from inside the engine air filter) and had zero problems. I’ve also noticed the engine coolant temperature runs a bit cooler now, which makes sense. And Newmar stepped up and paid the $1500 mobile service bill (after a lengthy letter by Karla to Freightliner was forwarded).
