Winterizing your RV protects the plumbing from freezing, but it is only one part of preparing your RV for several months of storage.
Once the water system has been properly drained and protected, there are still appliances, batteries, seals, tires and interior spaces that need attention. Leaving these areas unchecked can lead to unpleasant surprises when you are ready to go camping again.
A few extra hours of preparation in the fall can help protect your RV from moisture, battery failure and preventable spring repairs.
Winterization is only the first step
Many RV owners think winter preparation ends when the antifreeze has been added and the tanks have been drained. In reality, a properly stored RV needs attention well beyond the plumbing system.
Before putting your RV away, consider the following:
Plumbing and water heaters.
Appliances and water-connected accessories.
Batteries and electrical systems.
Tires and suspension.
Roof, windows and exterior seals.
Interior moisture and ventilation.
Food, waste and pest prevention.
Propane and fuel systems.
Protect the battery system
Cold weather can be hard on RV batteries, particularly if they are left partially charged.
Before storage, inspect the batteries and clean any corrosion from the terminals. If your RV will be stored for an extended period, follow the battery manufacturer’s recommendations for disconnecting, removing or maintaining the batteries.
Depending on your RV and storage location, you may use:
A battery disconnect switch.
A properly rated maintenance charger.
Solar charging equipment.
Battery removal and indoor storage.
Do not assume that turning off the main power switch disconnects every electrical load. Some systems, including alarms, control boards and tracking devices, may continue drawing power.
Prepare the tires
RV tires can develop problems when they remain in one position for a long period of time. Before storage, inspect each tire for cuts, cracking, uneven wear and signs of age.
Check the inflation pressure against the manufacturer’s recommendations. Do not rely only on how the tires look, because an underinflated tire may not appear obviously low.
If possible:
Park on a firm, level surface.
Avoid standing water and poor drainage.
Protect tires from prolonged sunlight.
Use suitable tire covers when appropriate.
Avoid placing excessive strain on stabilizer jacks.
Never use stabilizer jacks as a substitute for proper support, and never rely on them to lift or support the entire RV unless the manufacturer specifically allows it.
Keep moisture under control
Moisture can cause as much trouble inside an RV as freezing temperatures can cause in the plumbing.
Condensation may collect in closets, under mattresses, inside cabinets and around windows. Over time, that moisture can contribute to mould, mildew, odours and material damage.
Before closing the RV for the season:
Remove wet clothing, towels and bedding.
Clean and dry the refrigerator.
Leave refrigerator doors open with the proper latch.
Open selected cabinet doors to improve airflow.
Use moisture-control products where appropriate.
Inspect for existing leaks or damp areas.
Avoid sealing the RV so tightly that air cannot circulate.
If you use a dehumidifier or powered moisture-control device, make sure it is suitable for unattended use and that the storage location has a safe, reliable electrical supply.
Do not forget the appliances
Several RV appliances may require their own storage procedure. This is particularly true when an appliance uses water or has internal components that can retain moisture.
Depending on your RV, check the manufacturer’s instructions for:
Tankless and tank-style water heaters.
Ice makers and refrigerator water dispensers.
Washing machines and dishwashers.
Outdoor showers and spray ports.
Black tank flush systems.
Water filters and filter housings.
Furnaces and air-conditioning systems.
A water filter housing, for example, may still contain water even after the main plumbing system has been drained. Leaving the filter installed can also make spring start-up more difficult.
Tankless water heaters deserve particular attention because their internal passages and heat-exchanger components may require a specific draining, bypass or antifreeze procedure. Never assume that the procedure for a previous RV will work for a different water heater.
Check propane and fuel systems
Before storage, inspect propane cylinders, valves, hoses and fittings for visible damage. Close the propane supply according to the RV and appliance manufacturer’s instructions.
If your RV has a generator or fuel-powered equipment, follow the manufacturer’s storage procedure. This may involve fuel stabilization, running the equipment for a specified period or arranging for professional service.
Never perform fuel or propane work in an enclosed space without proper ventilation. If you notice an odour, damaged hose or suspected leak, stop and have the system inspected by a qualified technician.
Do not wait until freezing temperatures arrive or storage facilities are fully booked. Contact the Traveland RV team to schedule your winter storage preparation and start the next camping season with fewer surprises.
