Yeah... you can get 'water cans' at wal-mart still but they are not labeled gas. 4WheelParts & CEntral 4wd sell Jeryy Cans for gas/water still too, pricey but they do. I have 2 w/a rack for a ice chest on the rear of the jeep.

About the quad... you mentioned 60 miles on 1 tank, then you coudl carry more gas and refuel.... Could you safely go 150 miles a day without worry of burning up the motor? I don't know much about quads so I`m curious.
