It holds 120 US gal with standard range tanks and 160 US gal with long range.
Hot prop and boots, certified for known icing. Dual everything.
Without checking the POH it works out 4 and bags for full fuel and if 6 people the fuel load has to come down but to something that is still bladder busting.
I am going to Sweden next week 4:10hrs 850nm 63 US gal of fuel according to flitestar.
