Be careful Brad. If the auto-fill malfunctions and fails to cut off when the tank is full you have a big mess on your hands. Happened to me at Cape Blanco last October while I was spending the month there volunteering as a lighthouse docent. It kept going after the fresh water tank was full, ruptured the fill hose, and leaked water into the trailer. Of course that happened the first week and we spent the rest of the month without running water.
It may have been due to high pressure from the city water connection. I didn't have a pressure regulator then (do now) as I had understood the trailer had one built-in.
When I had things repaired at an AS dealer I had them disable the auto-fill "feature" as I'm not a big fan of automatic stuff.
