If you do not use the fresh water tank at all and it is empty, don't worry about sanitizing it. Wait until you have a need to use it before doing that job. The tank is isolated from the rest of the plumbing and is not used except by the internal pump.

Draining it is simple. Inside the basement there is a valve to drain it. You'll have to follow the line as it goes towards the floor of the basement behind the sliding door. The factory put the valve just above the floor covering and buried in the insulation in the case of my rig. Simply open it and leave it open until water no longer drains out. It will take a while as this never seems to drain very fast at all. Once it's dry close the valve and forget it.

If you find you will need the tank soon, sanitize it then other wise you are just wasting the effort.
