There are two higher time C208s but the rest are still relatively new, purchased with low-time used. They are all equipped with Garmin 530/430s.
Obviously, the aircraft is TCDS'd as single pilot, so as a few pax 135's do they have the OpSpecs auth for single-pilot with a working autopilot. I'd say 97% of the flights are 2-pilot. As far as Chief Pilot I'd say it is still open, but I'm not too sure.
You can shoot me a PM if that is easier for you.
