I MEAN to turn the water off at the spigot when we're gone & at night but seldom remember to do so. I do (most of the time) turn off the water heater.
I think the only thing worse than having your RV flood would be to wake up in a house boat and step in water when you crawled out of bed. That happened to me during our boating years because I didn't turn the water off & the hot water tank leaked. I will NEVER forget the feeling of water squishing up between my toes that morning! The hold filled with water and because the stateroom was 2 steps lower than the living area, it, the head and a couple of closets got wet. Took hours to pump it out...what a mess!
