I'm new to camping, but have been boating all my life. On our boat we use an outside filter and drink, etc. from the dockside or holding tank. In our new V-Lite, we spent three months last fall in VA, NY, NJ, MASS - Filtered outside (like on the boat) and also the KW1 internal filter - Neither my wife or I had any problems.
I occasionally use "bottled water", but it's more of a habit. I agree that we've become "sissyfyied" when it comes to drinking water.
