This is what I do for my camper.
Mine didn't have the hose to put in the antifreeze.
-Remove hot water tank plug if not already out.
-Turn water bypass switch on. (This was located under the sink at my hot water tank. You don't want antifreeze going into your hot water tank.)
-Pour 4 gallons of antifreeze into the holding tank. (I also open the holding tank drain till I see antifreeze just in case any water is left in the line)
-Turn on water pump.
-Turn on both hot and cold water taps at every station till antifreeze comes out. (Sink, shower, bathroom sink, outside shower)
-Flush toilet till antifreeze comes out.
-Take another gallon of antifreeze and pour down all sinks so no water left in the piping traps.
-REMOVE ALL FOOD FROM CAMPER!! If mice smell food they will be in there. I even vacuum the cupboards out when empty.
-Open up fridge doors and prop open. (My fridge has a little lever that I can slide open to prevent the doors from shutting.)
-Disconnect battery and store in a warm dry place. (do not leave directly on ground)
-It wasn't mentioned but I do this also. Crawl under the camper and look for any openings that mice may potentially crawl into. Spray foam any openings closed. (Ex. My battery container has a 2" hole for air to vent. I put in steel wool to prevent rodents from entering)
