Wasn't it the most stolen aircraft in the US for ages? Something about enough gas to fly to Colombia (or back), enough luggage space for big bags of horticultural crops and small bags of white powder, and a slow enough approach speed to land at any rough desert airstrip or make ditching in the Gulf of Mexico a bit less than a suicidal proposition.
Spent most of my early twin hours in Aztruks flying 5 pax and their bags out of an 800m strip. Glad I never lost an engine and good job it was only on short flights. Don't remember ever filling the tanks right up...think that made it good for about 6 hours.
You don't want the door to come open in flight though. Gives you a nasty fright and is almost impossible to close again......latches were always dodgy and bloody passengers have to play with everything!
Ah, the olden days, best flying of my carreer
