We've had so many issues with skanky water from rural city systems that we leave home with a full potable tank of our city's high quality water (5th in the nation for quality). We use the CG pressure supply for non-drinking/cooking, but carefully monitor the on-board potable supply as we travel.
Most trips we take are short enough that our potable tank provides all our drinking water. We have had a couple of incidents on the Oregon coast where the potable tank was empty. One particular CG was so bad, we drank wine and beer, even for breakfast, and dumped the tank at the first opportunity.
