A36 = 150
C210 = 150
C206 = 120
1.0 60L burn of fuel
1.0 60L burn of fuel
1.2 75L burn of fuel
C206 will be more expensive and time consuming to get there.
C210/A36 increased costs with retrac especially the A36 which is expensive to maintain and carries a smaller payload than a 210/206.
C206 would be the winner IMO
Considered an Airvan?
