I keep my sewer hose in the same compartment as the drain. Just get a hose that can start bending really close to the connector. My old Rhino hose wouldn't work. It went straight a few inches before it could bend. I also added a Tornado tank flush on my black tank. There's plenty of room to install it easily on the side of the tank. I've seen those keypad locks. That would be nice. Sorry I haven't answered your other message. I haven't had a chance to go look inside mine.
