I got the information from the Owners Manual that came with the unit. In Plumbing under Winterizing. I have only done it once because we camp year round but I used the short hose that came with the rig connected to the City water connection and inserted in the gallon of RV anti freeze. Prior to that, I blew the lines out with water pressure per the instructions. Make sure the water heater is by passed and drained before adding anti freeze. There are 2 methods detailed. One with air pressure and the other with all anti-freeze.
It appears easier than other rigs I have owned because all the valves are right in one spot except for the low point drains. They are all over.
