Our old RV had a fresh water tank and 1 faucet...piece of cake. The new one supposedly has a water heater bypass, but its not real accessible.

The local hardware store had a sale on Peak RV -50 antifreeze for $1.43 a gallon. Bought 12 gallons. Should cover the boat AND the RV.

So, how about I drain the fresh, grey and black tanks, and the water heater. Then add 8 gallons to the fresh water tank. Next turn on all the faucets to the sink, tub and toilet. That should flush everything, and all the water will go to the grey and black tanks so they will be flushed as well. Then, drain everything again. Finished!

I'm not concerned about wasting AF - For 12 bucks how can you go wrong? Any reason my logic is flawed?

You lost me. I use about 2 gallon every time I winterize.

I used to use only 1 gallon for my old trailer. Since the HW tank hold 6 gallons, I figured you needed at least 6 gallons in the fresh tank to fill the HW tank.

I don't know how to explain it better, so if you're still lost let me know and I'll explain more.
