Is It Better to Cover an RV in the Winter or Not?

If you own an RV, winter prep is how you protect your investment. One of the biggest questions that comes up year after year is whether or not to cover your RV during the colder months. Some RV owners won’t store their rig without a cover, while others avoid them entirely. So, who’s right?

The answer isn’t one-size-fits-all. Covering your RV can offer real protection from snow, ice, and UV damage, but it can also create new problems if not done correctly. Add in the cost, the time it takes to install, and the wide range of storage options out there, and it’s no wonder RVers are split on the issue.

Before you make the call, it’s worth understanding the real impact a cover (or lack of one) can have on your RV’s condition, time, budget, and peace of mind.

Benefits of Covering Your RV During Winter

Winter weather can do real damage to an RV if it’s left exposed. Between freezing temperatures, snow, rain, and UV rays, even a few months of unprotected RV storage can lead to costly repairs. That’s why many RV owners choose to cover their rigs during the off-season. A quality RV cover acts like a protective shell, helping preserve your vehicle while it’s not in use.

Below are the key benefits of covering your RV in the winter and why it might be worth the effort:

Shields the roof from snow and ice buildup: Heavy snow and ice can sit for days or weeks on the roof, adding pressure and allowing moisture to seep into seams and seals. Over time, this can lead to soft spots, leaks, or even structural damage. A properly fitted cover helps prevent snow from accumulating directly on the surface, reducing the risk of long-term water damage.
Blocks UV rays that cause fading and cracking: UV exposure doesn’t stop in winter. Even on cloudy or cold days, sunlight can wear down your RV’s paint, decals, and rubber seals. Over time, this leads to faded surfaces, brittle materials, and a more weathered look. A UV-resistant cover acts as a barrier, protecting your RV’s exterior from sun damage year-round.
Helps prevent water intrusion: Snow and rain can find their way into vents, window frames, and roof seams, especially if your RV already has minor cracks or loose seals. Once inside, that moisture can cause mold, rot, or rust. A waterproof or water-resistant cover helps keep the elements out and protects the integrity of your RV’s structure.
Keeps the RV exterior clean: Tree sap, bird droppings, wind-blown dirt, and falling leaves can stain and damage your RV’s surface. A cover keeps all of that off, so when spring rolls around, your RV needs less cleaning and looks closer to how you left it.
Maintains long-term value: RVs that are protected from the elements tend to age better. Paint lasts longer, seals stay tight, and fewer repairs are needed over time. Well-maintained RVs hold more resale value compared to those stored outdoors without protection. If you plan to sell or trade-in your RV someday, that extra care pays off.
Protects tires from cracking and dry rot: Tires suffer when exposed to the sun and cold for extended periods. UV rays can dry out the rubber while freezing temperatures can cause the material to stiffen and crack. UV damage and temperature swings reduce tire life by 25 to 30% if not protected. Covers that include tire flaps or are paired with separate tire covers help shield tires from the elements and extend their life.
Deters pests from nesting inside: When temperatures drop, rodents and insects start looking for warm, enclosed spaces, and your RV can look like a cozy winter home. While a cover isn’t a complete pest-proofing solution, it limits easy access points and makes it harder for animals to get inside vents, undercarriages, or compartments.

Downsides of Using an RV Cover in Cold Weather

Covering your RV in the winter can be smart, but it’s not without its challenges. If the cover isn’t used correctly or if it’s the wrong type, it can create problems instead of preventing them. Cold weather brings its own set of risks, and it’s important to understand how a cover may work against you in certain situations.

Here’s a breakdown of the most common downsides to using an RV cover in winter:

Moisture can get trapped underneath: Even though RV covers are designed to keep water out, they can also hold moisture in, especially if they’re not breathable. When the snow melts, or humidity rises, condensation can build up between the RV and the cover. If that moisture has nowhere to go, it can lead to mold, mildew, or even delamination of the exterior.
Covers can rub against your RV’s exterior: Winter winds can turn a loosely fitted cover into a constant source of friction. As the cover shifts or flaps in the wind, it can wear away paint, scratch windows, or peel off decals. Even soft fabrics can cause damage when there’s repeated movement over time.
Cheap covers often don’t last more than a season or two: Budget covers may save money upfront, but they’re usually made from thin, non-reinforced materials that break down quickly in freezing temperatures. Once a cover starts to tear, it loses its protective qualities and can cause more harm than good.
Covers can be hard to install and remove in cold weather: Putting on a large RV cover isn’t always easy. It often takes two people, a ladder, and a fair amount of time, especially if snow or ice is already on the roof. Cold weather can make the material stiff and harder to work with. For many owners, this step alone becomes a barrier to using a cover consistently.
Improper covers can block airflow and cause condensation: Not all covers are made with built-in vents or breathable fabric. Without proper airflow, warm air from sunny days or interior moisture can get trapped under the cover, increasing humidity inside the RV. This can lead to fogged windows, musty smells, and mold growth inside cabinets and walls.
Rodents and pests can still find a way in: While covers can help deter animals, they don’t completely prevent infestations. Mice and squirrels can still access the undercarriage, crawl into vents, or even chew through soft cover material to find warmth inside. A cover alone won’t be enough without sealing entry points or taking other precautions.

Types of RV Covers

Choosing the right type of RV cover can make a big difference in how well your rig is protected during winter. The materials vary in durability, breathability, and weather resistance. Some are built for mild climates, while others are made to withstand heavy snow and intense sun.

Polypropylene RV Covers

Polypropylene covers are lightweight, breathable, and water-resistant, making them a common choice for RV owners in mild to moderate climates. The fabric allows moisture to escape, which helps prevent mold and mildew underneath.

However, these covers are less durable in high winds or extreme cold. On average, polypropylene covers the last two to three winter seasons before needing replacement. They’re budget-friendly and easy to find but not ideal for areas with heavy snow or freezing rain.

Polyester RV Covers

Polyester covers are stronger than polypropylene and hold up better against wind, UV rays, and moisture. They’re designed for long-term use outdoors and are often used by RV owners who store their vehicles year-round.

These covers resist fading and tearing better than lower-cost options and are well-suited for regions with harsh winters. Polyester covers consistently perform better in colder climates, especially when reinforced stitching is used.

Tyvek RV Covers

Tyvek covers offer premium protection, especially in snowy or sunny regions. Developed by DuPont, the material is designed to reflect UV rays while resisting water penetration. Tyvek is also breathable, which helps reduce condensation under the cover.

Tyvek covers are breathable and help stabilize temperatures when compared to uncovered storage. These covers are more expensive but often last up to five years or longer with proper care. They’re popular among RV owners who prioritize durability and want full-season protection without constant maintenance.

Custom-Fit RV Covers

Custom-fit covers are made to match your RV’s exact dimensions, giving you a snug fit with fewer loose spots. This tight fit helps reduce flapping in the wind and prevents water from pooling in low areas.

Depending on your needs, custom covers are often available in polypropylene, polyester, or Tyvek. While they are more expensive, they offer better protection and typically include zippered panels for easier access to doors and compartments.

Universal RV Covers

Universal covers are designed to fit a wide range of RV sizes and shapes. They’re more affordable and widely available but often lack the precision fit of custom covers. As a result, they may shift in the wind or leave areas partially exposed if not properly secured.

These covers are best suited for short-term storage or for RV owners in mild climates with less severe winter conditions. While they provide basic protection, they may not hold up well over multiple seasons.

How to Choose the Right RV Cover

Choosing the right RV cover depends on more than just size. The material, fit, climate, and even where you store your RV all factor into the decision.

Start by knowing your RV’s exact length and shape. Covers that are too tight can tear, and covers that are too loose can flap in the wind and cause surface damage. A proper fit helps reduce stress on seams and keeps water from pooling in low spots.

The material also matters. Polypropylene is lightweight and breathable but better suited for dry, mild climates. Polyester adds more strength and UV resistance, while Tyvek provides the best protection for cold and snowy conditions.

Your storage location plays a big role, too. If your RV is parked under trees, a waterproof and UV-resistant cover helps protect against sap, leaves, and falling debris. You’ll want added wind resistance and reinforced corners if it sits in an open lot. RVs stored in direct sunlight benefit from UV-blocking fabric that slows down fading and cracking.

If convenience matters, look for covers with zippered access panels. These allow you to check on your RV or get inside without removing the whole cover. Some higher-end options also include reinforced straps, elastic hems, and adjustable tension systems that help secure the cover even in rough weather.

For long-term storage, custom-fit covers offer the best overall protection. They reduce fabric movement, lower the risk of tears, and provide more complete coverage. While they cost more upfront, custom-fit covers can extend the life of your RV’s exterior by several years and reduce repair costs over time.

Ventilation is often overlooked, but it’s critical. Covers with built-in air vents allow moisture to escape and prevent condensation buildup. This feature helps reduce the risk of mold and mildew forming underneath, especially during temperature swings.

How to Properly Cover Your RV for Winter

Covering your RV for winter storage is about more than just tossing on a tarp. Doing it the right way helps prevent water damage, mold, scratches, and general wear while your RV sits through the cold season. Here’s how to do it step by step:

Step 1: Wash the RV thoroughly

Before applying the cover, completely wash your RV. Clean off dirt, leaves, sap, bird droppings, and road grime from the roof all the way down to the wheels. If left on the surface under the cover, they can cause stains, damage the paint, or mold growth.

Step 2: Let the RV dry completely

After washing, allow enough time for your RV to dry fully. Pay close attention to seams, window edges, and roof details where water tends to collect. A dry surface helps prevent moisture from getting trapped under the cover.

Step 3: Inspect and seal all seams, windows, and vents

Walk around your RV and check for cracks, gaps, or loose seals. Water intrusion from poor seals is the major reason for winter-related RV repairs. Reseal any areas that look worn using the appropriate RV caulk or sealant. This prevents water from sneaking in while the RV is in storage.

Step 4: Pad any sharp or high-friction areas

Use foam padding or soft cloth to cover sharp edges like ladder mounts, awning arms, antenna bases, or mirror brackets. This prevents the cover from tearing or wearing out at these points during wind or movement.

Step 5: Place the cover on the roof first

Fold the cover and bring it up to the roof. Unfold it carefully from the center, letting it drape naturally over the sides. Avoid dragging the cover across surfaces to prevent scratching or stretching the fabric.

Step 6: Adjust and align the cover properly

Once the cover is draped over the RV, align it evenly so it reaches all sides. Check that doors, windows, vents, and slide-outs are all properly covered and nothing is exposed.

Step 7: Secure the cover with all included straps and buckles

Use the straps provided to secure the cover around the body of the RV. Tighten them just enough to keep the cover in place, but avoid over-tightening, which can cause stress on the fabric or seams. Make sure the bottom edge is snug and won’t flap in the wind.

Step 8: Ensure proper airflow

If your cover has built-in vents, make sure they are open and positioned correctly. Good airflow under the cover helps reduce condensation and keeps the space dry.

Step 9: Cover the tires

Use separate tire covers if your RV cover doesn’t include tire protection. Exposure to cold and sunlight can damage the rubber, and covering the tires helps prevent cracking or wear during long-term storage.

Step 10: Check on the cover throughout the winter

After everything is in place, revisit your RV every few weeks. Brush off snow, clear debris, and make sure the straps are still tight. Catching small issues early helps avoid bigger problems later.

Alternatives to RV Covers for Winter Storage

While RV covers are a popular choice for winter storage, they are not the only option. Depending on your budget, location, and how long your RV will be parked, other solutions may offer better convenience, stronger protection, or less upkeep.

Indoor RV Storage

Storing your RV inside a fully enclosed building offers the highest level of protection. It keeps your RV out of direct sunlight, snow, rain, and wind while also reducing exposure to pests and temperature swings. Many RV storage facilities offer dedicated indoor units for RVs with climate control or at least shelter from extreme weather.

Indoor storage also reduces exterior wear and seal deterioration. The downside is the cost that can be higher in urban areas or during peak seasons. Still, it’s one of the most secure options for long-term protection.

Covered RV Storage

Covered storage offers a middle-ground solution. It’s typically a large open-air structure with an overhead roof and, in some cases, side panels. It protects the RV from falling debris, snow accumulation, and harmful UV exposure, but it may still leave it vulnerable to wind, moisture, and pests.

This option is often more affordable than full indoor storage while still delivering a significant improvement over storing your RV out in the open. RecNation specializes in both indoor and covered RV storage, offering gated access, wide drive aisles, and 24/7 surveillance. It’s a reliable alternative for RV owners who want serious protection without relying on a fabric cover.

Portable RV Shelters or Carports

Portable shelters are standalone structures that can be installed on your own property. They range from metal-framed carports to heavy-duty fabric enclosures. These can be a good long-term investment for RV owners who prefer to store their vehicles at home and want year-round protection.

Setup costs vary depending on materials and size, but once installed, portable shelters offer a reliable barrier against weather. Proper anchoring is essential, especially in areas with heavy wind or snow. A well-maintained portable shelter can provide years of protection with less hassle than managing a cover. It’s a practical alternative to using a cover and pairs well with a solid winterization of RV plumbing and power systems.

Storage with Onsite Services

Some RV storage facilities offer extras like monthly inspections, tire rotation, battery charging, or even pest control. While not a physical alternative to covers, these services help protect the RV’s condition during long stays. This option works especially well if you’re storing the RV in a region with unpredictable weather or plan to leave it untouched for the season.

Owners who use full-service storage solutions have fewer maintenance issues and a higher resale value than those using basic uncovered lots. It also gives peace of mind knowing the vehicle is checked on regularly.

Final Verdict

Winter can be hard on your RV, and how you choose to store it matters. Covering your RV offers clear benefits, from protecting the roof to keeping moisture and UV damage in check. Still, covers are not perfect, and alternatives like indoor storage or shelters may make more sense in some cases.

RecNation is built specifically for RV owners. Whether you need a place to store your rig during the off-season or want a secure solution year-round, they offer flexible storage options to match your needs. Their facilities include uncovered, covered, and fully enclosed storage units, so you can choose the level of protection that works best for your RV and your budget.

FAQ

Can I use a tarp instead of an RV cover for winter?

Using a tarp might seem like a cheap alternative, but it’s not recommended. Tarps don’t breathe, which can trap moisture and lead to mold or mildew.

What should I do with my RV tires before storing them for the winter?

Inflate the tires to the recommended pressure and cover them to protect against UV rays and cold exposure. Move the RV slightly every few weeks or use leveling blocks to reduce flat spots if possible.

Do I need to check on my RV during the winter?

It’s a good idea to check your RV at least once a month. Look for signs of water intrusion, pest activity, or shifting covers. Even if it’s stored at a secure facility, routine check-ins help you stay ahead of potential issues.

Does insurance cover damage during RV storage?

It depends on your policy. Some plans cover damage while in storage, while others do not. Check with your insurance provider to see if you’re protected against weather, theft, or rodent damage. If not, consider a storage-specific policy for added coverage.
