Just please try to keep them filled when it's sitting. Maybe overkill considering we've got fuel/water separators, but just like an airplane, I don't want water condensing in any Epic's tanks.
The 43 gallons in our S22 goes a nice long weekend of cruising and riding. 43 gallons times like $3.50... Last year I boned up twice and had to buy fuel in Havasu Marina Chevron - it was like $3.75. A pair of twenties don't go very far there!
