I was winterizing the trailer the other day (I'm trying the compressed air method) and noticed that the water heater retained at least a qt of water in the bottom.
I found a short piece of 1/4 nylon icemaker line and the natural curve allowed me to siphon off the last of the water via the drain bung at the bottom of the tank.
