the water from you FW tank? I've read where some people don't and i don't understand why not. If you have sanitized your system what is there to be afraid of??
We bring bottled water, its not a problem to do so, so we do. I would not have any problem drinking from the water tank, but the bottles are very convenient to have outside, to take along in the boat, lots of plus to having bottled water. We usually have one ice chest with water and pop, the little ones can get their water or pop when they want.
