I can't help but chime in on this thread. There are a few great video by the RV Geeks around the best practices to keep your tap water safe and fresh. Everyone here seems to know their stuff when it comes to traditional solutions but there is a brand new option for this now with a technology that turns your RV into a full blown water treatment center like you see in major cities. Never worry about microbial contaminants that come from your campsite water hookups again.
