Yeah, pretty difficult to do — rare occurrence. Only time it’s come close for me was staying overnight at family’s home where I was able to refill fresh water without being able to dump. Even then there’s no point in having extra fresh water if other tanks are nearly full, unless maybe for taking outside shower or washing toys.
