I currently fly one in North Carolina and it weighs about 6500 pounds with all medical equipment installed including a 42 lb full lox orb. That leaves you 1900 lbs of gas and people for a max gwt of 8400. In the summer 8400 is a bit optimistic but when it's cool you'll be fine.
You must plan ahead as there is not a lot of power to spare and parts are scarce as hens teeth as well as expensive.
That said, I like it and have flown it since 2001 with no trouble, good IFR ship too.
Fly Safe!
