How to Safely Store Your RV for Winter in Boise Idaho

Owning an RV in the Treasure Valley provides access to mountain getaways river trips and open road travel throughout the warmer months. Boise is a popular starting point for RV owners traveling to places like Island Park exploring Yellowstone National Park or heading north toward Coeur d Alene and the lakes of northern Idaho. When winter arrives preparation becomes necessary. Freezing temperatures snowfall and prolonged cold spells can cause damage if an RV is stored without proper care.

Winter RV storage requires attention to multiple systems and surfaces. Preparing your RV correctly reduces the risk of mechanical issues water damage and interior deterioration. The following steps focus on winter conditions common in Boise Idaho and outline how to prepare your RV for seasonal storage at Simply Storage.

For those in a hurry

•  Wash the exterior and clean the interior before storage
•  Remove all food and clean the refrigerator with the door left open
•  Inspect exterior seals roof surfaces and repair any damage
•  Change the oil fill the fuel tank and add fuel stabilizer
•  Check coolant levels for freezing temperature protection
•  Drain all water tanks and winterize plumbing with RV antifreeze
•  Inflate tires to recommended pressure and use tire covers
•  Disconnect or remove the battery and maintain charge
• Seal openings and use deterrents to prevent pest entry
• Allow ventilation and use moisture absorbers inside the RV
• Perform a final walkaround before locking the RV

Start With a Complete Cleaning

Cleaning and organizing your RV before winter storage helps prevent long term damage. Dirt dust and road residue left on the exterior can trap moisture once temperatures drop. Wash the entire exterior including the roof. In Boise fallen leaves pine needles and windblown debris often collect around vents and seams which can hold moisture against seals.

Inside the RV remove all food items including dry goods and canned products. Cold weather drives rodents to seek shelter and any food source increases the risk of infestation. Vacuum flooring clean seating surfaces and wipe down all counters cabinets and tables. Clean the refrigerator thoroughly and leave the door slightly open to prevent odors and mold from forming during storage.

Inspect and Handle Maintenance Issues

Before placing your RV into storage inspect all exterior seals around windows doors roof vents and slide outs. Boise winters involve repeated freeze and thaw cycles which can worsen small cracks or weak seals. Addressing these issues beforehand reduces the chance of moisture entering the RV while it is parked.

Examine the roof closely for damaged sealant or soft areas. Repairing these problems prior to storage helps prevent leaks caused by snow accumulation and melting. Inside the RV check ceilings walls and storage compartments for signs of moisture or discoloration and correct any issues found.

Prepare the Engine and Mechanical Systems

The engine and drivetrain require protection even when the RV is not in use. Begin with an oil and oil filter change. Fresh oil reduces the risk of internal corrosion during extended periods of inactivity.

Fill the fuel tank and add a fuel stabilizer designed for storage. This helps prevent fuel breakdown and reduces condensation inside the tank. Run the engine briefly to circulate the stabilizer through the system.

Check coolant levels and confirm the antifreeze mixture is rated for freezing temperatures common in Boise. Proper coolant protection helps prevent engine and radiator damage during cold weather.

Winterize the Plumbing System

Water systems are highly vulnerable to freezing temperatures. Drain the fresh water tank gray tank and black tank completely. Open low point drains if equipped. After draining remove remaining water from the lines using compressed air or by following manufacturer instructions.

Add RV approved antifreeze to all plumbing components including sinks showers drains and the toilet. Automotive antifreeze should not be used in RV water systems. Proper winterization protects pipes pumps and valves from cracking and failure.

Protect Tires During Storage

RV tires support heavy weight even when parked. Long periods of storage can cause flat spotting or uneven wear. Inflate tires to the manufacturer recommended pressure before storage.

Use tire covers to protect against sun exposure snow and ice. Even in winter ultraviolet light and temperature changes can degrade rubber. Storing your RV on a paved or gravel surface helps reduce moisture exposure compared to soil or grass. Simply Storage provides maintained storage areas suitable for RV parking.

Care for the Battery

Cold temperatures reduce battery capacity over time. Disconnect the battery before storage. If possible remove it and store it in a dry location protected from extreme cold.

If removing the battery is not practical use a battery maintainer to keep it charged. Periodically checking the battery during winter helps preserve its lifespan and improves reliability when the RV is placed back into service.

Prevent Pest Entry

Rodents and insects seek shelter during Boise winters and RVs can provide easy access if not sealed properly. Inspect the exterior for openings around utility connections vents and access panels. Seal gaps where wires or hoses enter the RV.

Install vent covers that allow airflow while preventing animals from entering. Inside the RV avoid leaving paper fabric or other materials accessible. Place deterrents in storage compartments and near entry points to discourage nesting.

Manage Interior Moisture and Airflow

Although Boise has a relatively dry climate moisture can still accumulate inside an RV without ventilation. Use vent covers that allow airflow while keeping out snow and rain. Place moisture absorbing products in cabinets closets and sleeping areas to help control humidity.

Avoid sealing the RV completely airtight. Limited airflow helps protect interior materials and reduces the chance of mold or mildew development.

Perform a Final Storage Check

Before leaving your RV in storage complete a final walkaround. Confirm tire pressure verify that windows doors and storage compartments are secured and ensure the refrigerator is turned off with the door propped open. Double check that the plumbing system has been fully winterized.

Remove valuables and personal documents lock the RV and record the storage location details for future access.

Storing an RV for winter in Boise Idaho requires preparation due to freezing temperatures and snow. Cleaning inspection mechanical care plumbing winterization and pest prevention all help protect your RV during the off season.



Using a dedicated RV storage facility such as Simply Storage provides additional protection through secure access and maintained grounds. Proper preparation helps preserve your RV and ensures it is ready for use when warmer weather returns.
