Should You Cover Your RV in the Winter? The Definitive Answer

The short answer to “should you cover your RV in the winter?” isn’t a simple yes or no. It depends on several factors, including your climate, storage location, RV type, and the quality of the cover itself. However, for most RV owners storing their vehicle outdoors, a proper cover is a wise investment.

Let’s explore the arguments for and against, helping you make an informed decision about this crucial aspect of RV winter care.

The “Yes” Argument: Benefits of Should You Cover Your RV in the Winter

When chosen and installed correctly, an RV cover offers significant advantages.

  • Protection from UV Rays: Prolonged sun exposure can degrade your RV’s exterior, fading paint, cracking decals, and damaging rubber seals on windows and roofs. A cover acts as a shield, preserving your RV’s aesthetic and structural integrity.
  • Defense Against Environmental Damage: Snow, ice, rain, hail, tree sap, bird droppings, and industrial fallout can all wreak havoc. A cover provides a physical barrier, preventing these elements from accumulating and causing corrosion, stains, or physical damage.
  • Reduced Oxidation: Metal and fiberglass surfaces can oxidize over time, leading to a dull, chalky appearance. Covering helps slow this process, keeping your RV looking newer for longer.
  • Pest Deterrent: While not foolproof, a well-secured cover can make it harder for rodents and insects to find entry points and set up winter homes inside your RV.
  • Maintained Resale Value: An RV that looks well-maintained and shows less wear and tear from the elements will command a better price when it’s time to sell.

The “No” Argument: Common Problems with Should You Cover Your RV in the Winter

Despite the benefits, improper use or selection of an RV cover can lead to its own set of problems.

  • Moisture Trapping and Mold/Mildew: A non-breathable cover can trap moisture underneath, creating a humid environment ripe for mold and mildew growth on your RV’s exterior and even within its structure.
  • Abrasion and Scratches: Wind can cause the cover to flap and rub against your RV’s surface, leading to scratches, scuffs, and paint damage, especially on sharp edges or protrusions.
  • Damage to the Cover Itself: Poor-quality covers can tear or degrade quickly, especially in harsh weather, making them a recurring expense.
  • Inconvenience: Installing and removing a large RV cover can be a cumbersome and time-consuming task, often requiring two people.
  • False Sense of Security: A cover doesn’t replace proper winterization. You still need to drain water lines, protect batteries, and secure the interior.

Ultimately, the decision to cover your RV should factor in these pros and cons. If you choose to cover, doing it right is paramount.

Understanding RV Covers: Types and Materials for Smart Winter Protection

Not all RV covers are created equal. Choosing the right one is crucial for effective winter protection. This is a key part of “how to should you cover your RV in the winter” effectively.

Breathable Fabric Covers

These are generally the recommended choice for RVs stored outdoors. They are made from materials like polypropylene, spun-bond olefin (often branded as Tyvek), or composite fabrics.

  • Key Feature: They allow moisture vapor to escape while still repelling liquid water. This breathability is vital in preventing mold and mildew.
  • Durability: Higher-quality breathable covers often feature multiple layers for enhanced durability and UV resistance.
  • Fit: Available in both universal and custom-fit options.

Heavy-Duty Tarps (and Why to Avoid Them)

While seemingly a cheap solution, generic tarps are almost always a bad idea for RV winter storage.

  • Non-Breathable: Tarps trap moisture underneath, creating a greenhouse effect that promotes mold, mildew, and corrosion.
  • Abrasion Risk: Their stiff, abrasive material, combined with wind, will quickly scratch and damage your RV’s finish.
  • Poor Fit: They rarely fit snugly, leading to excessive flapping and potential tearing.
  • Weak Tie-Downs: Grommets often tear out easily, leaving your RV exposed.

Resist the urge to save a few dollars with a tarp. It’s a short-term saving that can lead to long-term, costly damage.

Custom-Fit vs. Universal Covers

When considering “should you cover your RV in the winter guide,” the fit matters.

  • Custom-Fit Covers: Designed precisely for your RV’s make, model, and length.
  • Benefits: Snug fit minimizes flapping and abrasion, often has specific cutouts for doors or access panels, and provides superior protection.
  • Drawbacks: More expensive and less versatile if you change RVs.
  • Universal Covers: Designed to fit a range of RV sizes.
  • Benefits: More affordable and widely available.
  • Drawbacks: May not fit as snugly, potentially leading to more flapping and less protection. Can still be effective if sized correctly for your RV.

Always measure your RV’s length, width, and height (including AC units and other roof protrusions) before purchasing any cover.

Preparing Your RV for Winter Storage: Beyond Just Covering

A cover is just one piece of the winterization puzzle. Before you even think about installing a cover, you must properly prepare your RV for its long winter nap. This is a critical step in any “should you cover your RV in the winter care guide.”

Winterizing the Plumbing System

This is arguably the most important step to prevent costly damage from freezing water.

  • Drain All Water: Empty fresh water tanks, grey tanks, and black tanks completely.
  • Bypass Water Heater: Use the bypass kit to avoid filling your water heater with antifreeze. Drain the water heater tank.
  • Blow Out Lines: Use an air compressor (regulated to 30-50 psi) to blow all water out of your lines, faucets, and toilet.
  • Add RV Antifreeze: Pour non-toxic RV antifreeze into all water lines, drains, and the toilet bowl. Run faucets until pink antifreeze appears. Don’t forget the outdoor shower!

Never use automotive antifreeze in your RV’s plumbing system – it’s toxic!

Protecting the Interior

The inside of your RV needs attention too, especially if it will be sealed up for months.

  • Clean Thoroughly: Remove all food items, especially perishables. Clean surfaces to deter pests.
  • Remove Valuables: Take out anything susceptible to extreme temperatures or theft.
  • Moisture Control: Place moisture absorbers like desiccants (e.g., DampRid) in various areas to combat humidity and prevent mold.
  • Ventilation: Crack cabinet doors and interior doors to allow air circulation. If possible, leave roof vents slightly open (and covered) to allow some airflow.

Battery Care

RV batteries can suffer significantly in cold weather if not properly maintained.

  • Charge Fully: Ensure all batteries (house and chassis) are fully charged.
  • Disconnect: Disconnect the negative terminals to prevent parasitic draws.
  • Remove and Store (Optional but Recommended): For optimal care, remove batteries and store them in a cool, dry place where they won’t freeze. Use a trickle charger to keep them topped off throughout the winter.

Tire Preservation

Tires are susceptible to dry rot and flat spotting during prolonged storage.

  • Inflate to Max PSI: Inflate tires to the maximum recommended PSI to help prevent flat spots.
  • Block or Jack Up: If possible, lift the RV off its tires using jacks or blocks to take the weight off the tires.
  • Cover Tires: Use specialized tire covers to protect them from UV degradation and cracking.

Addressing these critical steps ensures your RV is truly ready for winter, whether you cover it or not.

Best Practices for Covering Your RV in the Winter

Once your RV is thoroughly winterized, it’s time to apply the cover. Doing this correctly is essential to maximize the “benefits of should you cover your RV in the winter” and avoid the “common problems.”

Cleaning and Repairing Before Covering

A clean RV is a happy RV, especially under a cover.

  • Wash and Wax: Thoroughly wash your RV’s exterior to remove dirt, grime, and environmental contaminants. Apply a good quality RV wax or sealant to add an extra layer of protection to the finish.
  • Inspect for Damage: Check for any sharp edges, loose trim, or protruding antennas that could tear the cover. Repair or pad these areas.
  • Roof Inspection: Ensure your roof is clean and free of debris. Check all seals and caulking for cracks and make any necessary repairs.

Proper Installation Techniques

This is where “how to should you cover your RV in the winter” really comes into play.

  • Work with a Partner: RV covers are large and unwieldy. Having a second person makes installation much easier and safer.
  • Start from the Roof: Fold the cover neatly and carry it to the RV roof. Unfold it lengthwise, then carefully drape it over the sides.
  • Protect Sharp Edges: Use old towels, pool noodles, or specialized padding on gutters, antenna bases, and other sharp points to prevent tears and abrasion.
  • Secure Tightly but Not Too Tightly: Most RV covers come with straps and buckles. Fasten them securely to prevent flapping in the wind, but avoid overtightening, which can stress the fabric or damage your RV.
  • Ensure Ventilation: Many quality RV covers have integrated vents. Make sure these are not blocked.

Take your time with installation. A rushed job can lead to tears, damage, or ineffective protection.

Ensuring Ventilation

Even with breathable covers, airflow is key. This directly addresses one of the “common problems with should you cover your RV in the winter.”

  • Use Integrated Vents: Ensure your cover’s ventilation ports are open and clear.
  • Consider Additional Airflow: If your cover doesn’t have ample ventilation, or if you live in a very humid climate, consider adding small, covered vents or props to slightly lift the cover in strategic areas (if feasible and secure) to promote air circulation.

Proper ventilation helps prevent moisture buildup, mold, and mildew, which can compromise both your RV and the cover itself.

Sustainable and Eco-Friendly RV Winter Care

At OutwardLab, we advocate for responsible outdoor living. “Sustainable should you cover your RV in the winter” and “eco-friendly should you cover your RV in the winter” practices are vital for minimizing your environmental footprint.

Reusable Covers and Longevity

Investing in a high-quality, durable RV cover is an eco-friendly choice in the long run.

  • Durability Over Disposable: A cover that lasts for many seasons reduces waste compared to cheap, single-use tarps that quickly degrade and end up in landfills.
  • Repair, Don’t Replace: If your cover gets a small tear, patch it rather than buying a new one. Many manufacturers offer repair kits or advice.
  • Proper Storage: When not in use, clean and thoroughly dry your RV cover before folding and storing it in a cool, dry place. This extends its lifespan significantly.

Environmentally Friendly Winterizing Fluids

The fluids you use for winterization matter.

  • Propylene Glycol-Based Antifreeze: Always choose non-toxic, propylene glycol-based RV antifreeze. It’s safe for your plumbing system and the environment if small amounts are discharged.
  • Avoid Ethylene Glycol: Never use automotive antifreeze (ethylene glycol) for your RV plumbing, as it’s highly toxic to humans, pets, and wildlife.

Minimizing Waste

From cleaning supplies to disposal, every small choice adds up.

  • Biodegradable Cleaners: Use RV-specific, biodegradable cleaning products for washing your rig before covering.
  • Proper Disposal: Dispose of any drained wastewater or used antifreeze responsibly according to local regulations.
  • Reduce, Reuse, Recycle: Apply the classic principles. Reduce unnecessary purchases, reuse materials like padding for sharp edges, and recycle packaging from your cover or winterizing supplies.

By making conscious choices, you protect your RV and the natural world you love to explore.

Troubleshooting Common RV Cover Issues

Even with the best intentions, you might encounter issues with your RV cover. Knowing how to address them is part of being an experienced outdoor enthusiast.

Mold and Mildew Prevention

This is a persistent concern, especially in humid climates.

  • Ensure Breathability: Reconfirm your cover is breathable and its vents are clear.
  • Interior Moisture Control: Supplement with interior desiccants.
  • Regular Checks: Periodically lift a corner of the cover on a dry, sunny day to allow air to circulate and check for any signs of moisture or growth.
  • Clean Before Covering: A clean RV surface is less hospitable to mold spores.

Wind Damage and Abrasion

Strong winds are a cover’s worst enemy.

  • Secure Straps: Ensure all straps are cinched tight enough to prevent flapping, but not so tight as to cause stress.
  • Pad Sharp Edges: Double-check that all potential abrasion points are well-padded.
  • Consider Wind Protection: If storing in an extremely windy area, consider positioning your RV to minimize direct wind exposure or adding extra tie-downs if your cover allows.

Pest Control

A cover can deter some pests, but determined critters will find a way.

  • Seal Entry Points: Before covering, inspect your RV’s underside and exterior for any small openings that mice or other rodents could exploit. Seal them with steel wool, expanding foam, or mesh.
  • Repellents: Place natural repellents like peppermint oil, dryer sheets, or mothballs (in contained areas) inside the RV.
  • Regular Monitoring: If possible, check inside your RV periodically throughout the winter for signs of pest activity.

Being proactive and performing regular checks will help you catch and resolve these issues before they become major problems.

Frequently Asked Questions About RV Winter Covers

How often should I check my RV under the cover?

Ideally, you should check your RV at least once a month. This allows you to inspect for moisture buildup, pest activity, cover damage, or any unexpected issues. Choose a dry, calm day to briefly lift a section of the cover and inspect.

Can I use a regular tarp instead of an RV cover?

We strongly advise against using a regular tarp. Tarps are typically non-breathable, trapping moisture and promoting mold/mildew. Their abrasive material can also scratch your RV’s finish due to wind flapping. Invest in a proper, breathable RV cover for effective protection.

Does covering an RV prevent rodent infestations?

An RV cover can act as a deterrent by making entry points less accessible, but it’s not a foolproof solution. Rodents can still find their way in. The best defense is to thoroughly clean your RV, remove all food, seal any exterior openings, and consider using repellents or traps inside.

What’s the best time to cover my RV for winter?

You should cover your RV once you’ve completed all your winterization steps and before consistent freezing temperatures or heavy winter precipitation begins. This typically means late fall or early winter, after your last camping trip of the season.

Will a cover damage my RV’s finish?

A high-quality, breathable RV cover, properly installed and secured, should not damage your RV’s finish. Problems arise from using non-breathable tarps, covers that fit too loosely (causing abrasion), or covers that are installed over a dirty RV surface. Always clean your RV and pad sharp edges before covering.

Deciding “should you cover your RV in the winter” is a nuanced decision, but with the right knowledge and tools, you can confidently protect your investment. By understanding the benefits, mitigating the risks, and following best practices for both winterization and cover installation, you ensure your RV remains in prime condition, ready for countless new adventures.

Remember, living outdoors smarter means being prepared and proactive. Take the time to properly care for your rig now, and it will reward you with reliability and comfort for years to come. Stay safe, stay comfortable, and keep exploring!
