Fresh Water Tank Level During Storage

[LOOMER]

I'm going to store my RV for about 3 months. Should I leave fresh water tank full, partly full, or empty?

I would leave it empty.

Welcome to the forum!  Three months storage with water in the tank is an invitation for algae and bacteria growth.  Empty the tank, drain all the lines and the water heater in the coach.  When you get ready to hit the road again, fill the tank, add chlorine, then run the chlorinated water through all the water lines and water heater, let it sit for an hour.  Drain everything and fill with fresh water.  You should be ready to go!

If you use hydrogen peroxide it will do the job without any after taste.  Pour 8 oz into the fill hose and then fill the tank with about 10 gallons of water.  Run each faucet until the treated water comes through.  When you are ready to use the system just fill the water tank full and use it.  No chlorine taste.
