You need an air compressor set to about 60 PSI and a air chuck fitting that connects to your incoming water line that looks like this.

Once you get setup, you just get some air connected and then open one faucet in the coach at a time to allow the air to blow all the water out of the system. You do this with the cold and the hot lines separately. You may need to do each a couple of times just to get the last bit but even a little water left behind will do no damage since any ice that forms will have plenty of room to expand and will not cause any issues. You will still need some RV anti-freeze and this you will pour into all of your drains which have a trap. Sinks, shower, washing machine to ensure the water in there is forced out and only anti-freeze left behind. I prefer this method to pumping anti-freeze everywhere since I don't have to flush any lines when I am ready to use the coach again, I just fill with water and go.
