Any use portable gas caddy?

[wacotiger]

I have a boat on Big Lake at my camp and I was thinking about buying a 14 gal gas caddy from Stine's. Anyone had any experience with them? Any trouble? Good deal? The only place I know to buy gas on Big Lake is at Hackberry. I burn about 30-35 gallons of gas when I fish and I think I would probably save save about $15 - $20 for each trip if I didn't buy gas on the water. Any thoughts or suggestions from those that use it or do something else? Thanks.
