Drongo Driver, the PC12 is weight limited at remote bases. Standard fuel load for some bases (1800lbs?) is way less than full tanks (2300lbs?). You could have onboard a pilot(essential!), flight nurse, doctor, up to two stretcher patients non stretcher patients, a police officer, or patient relative. So easily 6-7 persons. If you get retasked mid flight to a close destination you will be too heavy to land. Adding another pilot to the load doesn't really help in this regard.
