Hauling full water tanks

Small towns can be your friends. Most will have a potable water site and will allow you to fill for free.

I can't imagine a campground having a non-potable water supply at all.

I have seen many campgrounds with both.  The non potable is usually well marked, though.
Water can be potable, meeting all the sanitary standards, and still taste bad.

I'm going to be boondocking but my main concern is where can I find free potable water, any ideas guys and gals.

Ranger stations often have potable water available to the public.  Sometimes even dump sites.
