As for the OP, we have an older Volvo with the D12. Put a lot of money into the motor. I understand that's not common. It usually takes a Volvo garage for some of the engine work but I've had repairs done at Ford dealerships & many other independent shops.
Moresmoke nailed it when he said, find a dealership to work on your truck 24/7. I've been to truck shops that said to get in line your next or can you bring it in tomorrow? Yesterday I had a rear bag leak. Drove down to an independent truck shop with my car & was told to go get the truck, I'll put a guy on it.
