Diluting RV Anti-Freeze for Winterization
I have winterized two ways. My first winter in our B, I drained the fresh water tank and pumped RV anti-freeze into the tank. I then ran it through all the lines. This allowed use of the toilet. Howev...

The pump was most likely ruined because either it couldn't pump the RV antifreeze at below freezing temps or because it was diluted. At some point below freezing, the RV AF turns to thick slush about like a snow cone. The water pump isn't meant to pump slush.
If you have a jug of standard automotive engine antifreeze, look at the back of it, you'll see a mixing chart. The strongest mixture (for automotive antifreeze not RV antifreeze) is about 60% antifreeze and 40% water. As you add more water, the temperature you're protected to decreases or goes up. On RV antifreeze you never dilute it like you do automotive antifreeze. If you do, it looses its protective value and becomes worthless.
If all you lost was the pump, you were lucky. The pump is easy to change and takes about 30 minutes. Imagine the pain of trying to change out cracked water lines hidden behind the cabinets and underneath the floor.
