What's the endurance? Are there standard and long range tank versions?

Tanks hold 51 gallons usable, there are tabs to let you load 38 usable
so you get a little more useful load for pax+baggage. There's an STC'd
18 gallon aux tank available, it robs some space off the relatively small
baggage area so I never considered it.
