As long as it is filled with clorinated city water from our home I have no issues drinking from FW tank on our rig. Have had issues with poor water quality on too many occasions when RVing to trust drinking from unknown water supply sources, even though our rig came with a water filter.
It is the main reason we fill our dual FW tanks when dry camping and boondocking, yeah it's a lot of added weight but we don't want to put crappy water in our tanks, been there done that with our previous rig. For us RVing is our prime time living, why eat and drink items of inferior quality.
