Fics like Superphantom: The Ghost King, three hunters, and an Angel. (Temporarily on hiatus as I'm reworking/updating story).

After tons of years as the ghost king, Danny decided to take a road trip across the country both to take a small break but also to make sure the other spirits outside of Amity Park weren't causing too much trouble. While Danny is travelling around and getting into misfit he comes across both Bobby Singer and the Winchester gang who don't know he is the ghost king or that Danny is a ghost at all, they just think they had picked up a young scrawny teenager who wants to be a hunter.
