How to Winterize Travel Trailers

How to Winterize Travel Trailers
It's always important to winterize a travel trailer if you are going to put it into storage for the offseason. This protects the equipment from harsh temperatures during the winter and prepares the interior of the trailer for use the following spring. There are pests to be concerned about, such as mice and other rodents that might forage through your trailer in search of food. Winterizing a trailer is a long process, but it's not a difficult one.


Difficulty: Moderate

Step 1
Thoroughly clean the interior of the trailer. This will get it ready for use in the spring and also to remove anything that might attract animals, whether it is food or materials that might make a nest. Remove all food from the trailer, including pressurized foods. The pressurized foods won't be accessible by animals, but they could burst open in a drastic temperature change. Clean the rest of the kitchen, making sure to get under appliances for any crumbs. Empty the fridge and clean it out, leaving the door open to air out over the winter.
Step 2
Clean out the bathroom, removing toothpastes, shampoos and all other items. Wash down the bathroom thoroughly, including the toilet, sink and shower, to keep mold or mildew from developing in the offseason.
Step 3
Wash all linens and towels and either store them in your house or in plastic bags in the trailer.
Step 4
Empty out all water from your trailer, including the holding tank, fresh water tank and faucets. Run all faucets open with the tanks open until no water is running out of the RV. Drain the hot water heater.
Step 5
Refill all the water tanks and add 2 to 5 gallons of antifreeze, depending on the size of your trailer. Run all faucets, including the hot water tap, until the water coming out is colored by the antifreeze. Flush the toilet and run the shower until you see the same color change. Put antifreeze down your water drains and add an extra gallon to the holding tank when the faucets are flushed.
Step 6
Lower your trailer stabilizers and fill the tires to the upper limit allowed. Tire air pressure will decrease with colder temperatures.
Step 7
Close off all propane tanks and check the trailer's oil. Many people change the oil after the last use of the season. Remove the smoke detector and take out its battery and make sure everything, including appliances, tanks, heaters and lights, is off.
Step 8
Close all the vents, windows and doors on your trailer and lock the doors.
