Getting all the water out of the water heater
When you drain your water heater, and get ready to winterize your rig, do you remove ALL the water out of the water heater? There is usually about 1/2 gal or so left in it. There will not be any damag...

I drain all the water out. It has nothing to do with freeze damage but everything to do with the tank rusting out.
Many years ago I went to an RV clinic put on by my local dealer. The tech kad a water heater cut in half. This heater was about 10 years old and the tank had failed. The bottom 10% of the tank was rotten...... the top 90% looked good.
Think about this. When not using the RV you have water and air in the tank for half the year. The water is below the anode rod, so the rod will not work. This is a terrible situation for the water heater tank. My best guess is that almost all of the water heater tank damage occurs at the water line. Get all the water out for this reason.
