We're in CGB and have decided to go tomorrow to Scrub island so we'll grab fuel there. The electronic gauge says 30% of what according to specs is a 106 gallon tank. We have 3 more nights where we definitely will run the generator as well as some during the hot part of the day so we're probably ok.
Still I'd rather toss some diesel in there and not worry about running out before our turn-in on Thursday.
