I also have a place in the water bay for the sewer hose, but I have never used it because I don't think it would fit with the end connections. I can see where a hose without the connectors would fit, but how many RVers have the hoses without the connectors? Not to many, it would be a hassle screwing on a connector everytime you use the coach. So I have never used it. They should have made it bigger in diameter so that you could store the sewer hose with the connectors on.
