Is it crazy to leave water in your tanks in storage?

I am storing in Las Vegas so the coldest it gets at night are in the low to mid 20s for just hours at a time. I feel like it would be better for the rubber seals (keeping them moist) if I fill the grey and black tanks 1/2 full of water for storage. Do you think this is a good idea or not?

    When I gamble in Vegas, I lose. :B
    Why gamble on the weather, drain the tanks and winterize.

    You're storing your rig in Las Vegas. Gambling with the weather is your choice.
    Personally, I would drain the tanks and use RV Antifreeze as recommended above.
    Then you know the tanks won't freeze in the event of colder than normal weather.

    Water wont keep the seals pliable. They will be fine without anything in the tank.

    1/2 full probably won't hurt anything, but also unnecessary. The seals you're concerned about are at the very bottom of the tanks. I just pour enough antifreeze into the tanks to know some got down to the drain valves. I dump some in the toilet to keep that seal wet, and a bit into the drains.
