Just did mine yesterday. I made sure the black and gray tanks were empty. Here at the house, I have a macerator/pump to pump the tanks uphill to the septic tank clean out opening. If you have a sewer connection, gravity does a nice job. Also, if there is a fresh water tank, it must be emptied. If the units stay in the same place all year with connected water, the tank is probably empty. As for the water heater, you 1st operate the bypass valve and then pull the drain plug. It empties faster if you pop open the over pressure valve. Now you pump the pink antifreeze into all the water lines. I use the on-board pump, which is usually used to pressurize the water system when using the on-board water tank (now empty). I have a short length of hose that connects to the input of the pump. Normally, it connected to the fresh water tank, but you have to disconnect that. One end of the hose has a fitting for the input of the pump, the other end is just cut clean. The cut end goes into the jug of pink RV anti-freeze. You then enable the pump on the RV control panel and run every faucet, both hot and cold, until the pink comes out. The jug might have to be elevated a bit the get the pump to prime. Don't forget the toilet and any outside hand shower. Make sure enough of the pink stuff goes into each sink/show's trap. Alternately, you can pour a cup or so, into each trap, right from the jug. The toilet doesn't have a trap, so you only need to make sure the pink stuff fills the water pipe.
As my unit is a motor home, and because I use the generator as a backup for the house, I have a full 50 gallons of gas in the tank and it should be treated with a fuel stabilizer. And, again, because the generator might be used for emergency, the oil will be changed .... probably tomorrow. I like to put a battery tender on the house battery to keep it healthy. I don't let the normal power converter on, because some of them tend to over charge the house battery. Also, because it is a motor home, I have a 2nd battery tender on the vehicle battery. I also turn off the propane tank. I think that's it.
