Hello Everyone, I have a 2013 N Series Isuzu NPR-HD with 300,000 miles on it, and it will not re-gen (either on the road or parked). I have had it looked at several times, had the codes cleared, and had the filter burned clean recently. I am going to trade it in, but in the meantime; can I still run this truck for my deliveries even though it is powered down?
