I don't drink water when camping period.
Having dually I have no problem to load more adequate liquid.
That said, we always used tank water for consumption. Never sanitize the tank and usually, when in California I would have water in tank over the winter.
In Las Vegas now, we have very hard water, so I dump it for winter storage.
Our last camper has build-in water filter, so going to Alaska last summer, I bought new cartridge for it.
In the past I would cary Brita water pitcher for situation when water might not be safe.
Still remember camping years ago where campground water had nice brown color. Ironically the lake and campground belong to Sacramento Water District.
