Things You'll Need:
- A few gallons rv antifreeze (pink)
- Freshwater source
- Electric source
-
Step 1
Refer to the owner's manual to determine exact locations of each item in article. These will vary in each rv. Start by draining the hot water tank with the drain valve, usually located at the bottom of the water heater. If you have a bypass for the water heater, set it to bypass at this time.

Step 2
Pour a few gallons of antifreeze into the freshwater holding tank. The larger the tank and rv, the more that will be required. After filling, open all water sources (one at a time) until the pink flows through. Do not forget about the toilet. Run enough in the sinks so that the traps below will be filled with antifreeze. Leave just a little in the bowl of the toilet. If you have a dishwasher or laundry washer check owner's manual for specifics on how to winterize these appliances.

Step 3
Be sure the gray and freshwater water tanks and the holding tanks are all emptied. You will not need antifreeze in the holding tanks because there is plenty of room for the minimal amounts of moisture to freeze and expand. Finally change the water filter if applicable. This should take care of the "cabin" area of winterization.

Step 4
Before storage change the oil and filter, and air filter. Also change the cabin air filter if applicable. Fill the gasoline tank and add some fuel system water remover and antifreeze, and also fuel stabilizer. Keeping the gas tank full fights rusting of the gas tank. Be sure to add the fuel stabilizer to ensure gasoline stays good during off season. Cover, if desired, and store for the dreaded off season.
