How to Store an RV Outside Through Winter in Lake Country, BC

Parking an RV outside for winter takes more preparation than finding a space and locking the door. Water left in the plumbing can freeze, batteries need attention during months of inactivity, and the roof, seals, tires, and interior all need to be ready for an extended stay outdoors.

For owners comparing storage options in Lake Country, we at Okanagan Secure RV Storage offer both uncovered and covered RV parking at our property on Dick Road, near Highway 97. Some covered spaces also include power, and our facility has an onsite sani dump and wash bay, which are useful when you're preparing an RV for its winter stay. So, how do you store an RV outside in winter without creating problems for spring? Start with the systems most vulnerable to freezing and long periods of inactivity.

Winterize the Plumbing for Freezing Temperatures

The plumbing system deserves attention before anything else. Any water left inside tanks, pipes, faucets, or other plumbing components can freeze and expand. The exact winterization process varies by RV, so your owner's manual should determine the procedure for your particular model.

In general, winterizing starts by draining the fresh, grey, and black water tanks and removing water from the plumbing system. Depending on the RV manufacturer's instructions, that may involve blowing out the lines with compressed air, using RV antifreeze, or following a combination of steps. Go RVing Canada recommends opening the faucets while draining and making sure RV antifreeze reaches the faucets and drains when using the antifreeze method. 

Use antifreeze specifically intended for RV plumbing rather than automotive antifreeze. Water heaters also require their own draining and bypass procedure. Because systems differ between models, don't rely on a generic sequence if it conflicts with your owner's manual. Winnebago likewise advises owners to follow the instructions for their specific RV when winterizing. 

At our Lake Country property, the onsite sani dump gives RV owners a place to empty holding tanks as part of their storage preparation. For a broader look at preparing a rig before parking it, our guide to storing an RV in Lake Country covers cleaning, plumbing, batteries, tires, moisture, and other off-season considerations.

Clean and Dry the RV Before Parking It

Winter storage starts with a clean RV, inside and out. Road grime, dirt, and organic debris shouldn't sit against exterior surfaces for months. Pay attention to the roof, sidewalls, windows, wheels, trim, and areas around exterior compartments. Let the RV dry before putting it away. Trapping moisture under a cover or closing up a damp interior creates another problem while you're trying to solve the first one. Inside, remove food, drinks, trash, and anything else likely to attract pests. Vacuum floors and upholstery, wipe down food preparation areas, and clean out cabinets. The refrigerator and freezer should be emptied, cleaned, dried, and left according to the manufacturer's storage instructions. 

Inspect the Roof, Seals, and Exterior

Once the RV is clean, inspect the exterior while problems are easy to see. Look closely at the roof and the seals around windows, doors, vents, skylights, and other exterior openings. Cracked or deteriorated sealant should be addressed according to the RV manufacturer's maintenance instructions before the vehicle spends months outdoors. 

This inspection matters even if you plan to use an RV cover. A cover doesn't repair a failed seal underneath it. If you're choosing between uncovered and covered parking, think about how much direct exposure you want the RV to receive during the storage period. Covered outdoor parking provides an overhead structure rather than a fully enclosed building, reducing direct exposure to precipitation and other material falling from above. 

Decide Whether to Use an RV Cover

If your RV will be parked in an uncovered outdoor space, a properly fitted RV cover is one option for adding protection. Use a cover designed for RV storage and follow its manufacturer's installation instructions. Breathability matters because moisture trapped underneath a cover can contribute to mould and mildew. A poorly fitted cover can also move against the exterior in windy conditions. 

A cover doesn't eliminate the need to winterize, inspect seals, or prepare the interior. Those steps protect different parts of the RV. Covered parking changes the equation because a permanent canopy already provides overhead protection. At our property, covered spaces are available in several lengths, although availability changes and renters should check the current listings before choosing a space. 

Prepare the Batteries for Storage

An RV battery shouldn't simply be forgotten until spring. Your manufacturer's instructions should determine whether batteries are removed, disconnected, maintained with an appropriate charger, or managed another way. We recommend turning off disconnect and breaker switches when removing batteries and storing fully charged batteries in a dry location, while larger battery systems should be handled according to the owner's manual.

If you plan to maintain batteries while the RV is parked, check what your specific storage space provides rather than assuming electrical service is included. At Okanagan Secure RV Storage, select covered spaces come with 15-amp or 30-amp power. Power isn't included with every parking space. That distinction is worth checking before you rent, especially if your winter storage plan depends on having a power source.

Don't Ignore the Tires

Months in one position place different demands on RV tires than regular driving. Before storage, inspect the tires and set their pressure according to the RV and tire manufacturers' specifications. We recommend checking tire condition and inflation before putting an RV away. Consider tire covers for RVs stored outdoors to reduce direct exposure. The parking surface and procedures for long-term tire care depend on the vehicle, so follow the chassis, RV, and tire manufacturers' guidance rather than using a universal pressure or lifting recommendation.

Reduce the Chance of Pest Problems

A clean interior is the first line of defence against pests. Food, crumbs, paper food packaging, and other attractive materials should come out before storage. Then inspect the exterior for openings that need attention. Areas around utility penetrations, compartments, vents, and damaged seals deserve a look, but don't block an opening that the RV manufacturer says must remain ventilated. Avoid treating pest prevention as a reason to seal the RV indiscriminately. The goal is to correct unintended entry points while preserving the ventilation and safety requirements of the vehicle.

Manage Interior Moisture

An RV can be properly winterized and still develop interior problems if it's stored damp. Make sure wet towels, clothing, cleaning materials, and other moisture sources are removed. After cleaning the refrigerator and freezer, follow the appliance manufacturer's storage instructions. Mattresses and cushions should also be dry before the RV is closed for an extended period. If you use moisture-control products, follow their instructions and make sure they're suitable for an unattended RV. Ventilation settings should follow the recommendations for your model, particularly if you're using a cover.

Check the RV During Winter

Outdoor winter storage isn't necessarily a park-it-and-forget-it arrangement. Periodic checks give you a chance to notice a shifted cover, exterior damage, tire problems, moisture, or another maintenance issue before the RV sits that way for the rest of the season. Follow your RV manufacturer's guidance on snow accumulation as well. We advise owners storing outdoors to keep the roof clear of excessive snow rather than allowing accumulation to remain indefinitely. 

At our Lake Country property, customer gate access is currently from 6:00 a.m. to 10:00 p.m. daily, so renters have a defined window for checking their stored vehicle. The property also has gated entry, NOKE Smart Entry, and 24-hour security cameras among its features. 

Think About Winter Storage as Part of RV Ownership

Preparing an RV for winter does more than get it through a few cold months. Condition matters over the life of the vehicle. Exposure and deferred maintenance can affect exterior materials, seals, batteries, tires, and other components. That becomes relevant when you're thinking about the RV's long-term condition and eventual resale. Our article on RV depreciation and storage looks more closely at the relationship between condition, care, storage, and value. The practical lesson is simple: don't wait until spring to deal with a problem you can see in fall. Repair known issues, winterize according to the manufacturer's instructions, and put the RV away clean and dry.

Choosing a Winter Space in Lake Country

For an RV spending winter outside, the parking space is only one part of the plan. Plumbing winterization, battery care, tire preparation, exterior inspection, pest prevention, and moisture management still need to happen before the vehicle settles in for the season. At Okanagan Secure RV Storage, our property at 2651 Dick Road offers covered and uncovered parking for RVs, with an onsite sani dump and wash bay. Select covered spaces include power, and the property is located near Highway 97, a useful local connection for RV owners travelling through Lake Country and the wider Okanagan Valley.
