I would only disagree with the inline water filters. They have saved my bacon a couple of times while traveling. The worst was a campground that had just completed an upgrade and did not tell us we were the first folks to visit the new pads. I filled the fresh water and thought nothing more of it. Later the neighbor came by and asked if I had gotten any sand in my system. I looked at the filter and it was almost 1/4 full of sand. My coach was fine and his coach had a fresh water tank full of sand and the water pumps weren't working.
