Everything You Need to Know About RV Covers

Covering your RV can help protect it from sun, rain, snow, and debris. In this RV cover guide we explain what covers are and why they matter, outline the types of RV covers (materials, fit, and weather resistance), and share the benefits of using a cover. You’ll learn how to choose the best cover for your motorhome, travel trailer, fifth-wheel, or camper van, plus tips for use and maintenance and common mistakes to avoid.

What Are RV Covers and Why They're Important

An RV cover is a durable, weather-resistant protective layer designed to shield your RV—whether it’s a motorhome, camper van, travel trailer, or fifth wheel—when it’s not in use. These covers act as a first line of defense against environmental threats such as sun, rain, snow, dust, bird droppings, tree sap, and airborne pollutants that can stain or corrode your RV's exterior. Without a cover, prolonged exposure to these elements can lead to faded paint, cracked rubber seals, deteriorating roof membranes, and costly repairs over time.

By blocking harmful UV rays and regulating heat, a quality RV cover helps preserve the structural integrity of your vehicle. It prevents premature aging, keeps your roof and body panels from becoming brittle, and reduces the chance of water damage caused by leaks or ice buildup. Many RV covers are designed with reinforced corners and vent panels to allow air circulation, which reduces the risk of trapped condensation and mold growth during long-term storage.

RV covers also provide an effective barrier against pests. Rodents, birds, and insects often try to access roof vents, slide-outs, or utility bays—but a well-fitted cover makes those areas far less accessible. Whether you're parked in a campground or storing your rig for the winter, a protective cover helps maintain cleanliness, reduces your maintenance workload, and extends the life and value of your RV investment.

Types of RV Covers

RV covers vary by material, fit, and weather resistance. Here are the main differences:

• Material: Most RV covers use tough polyester, polypropylene or vinyl-coated fabrics. High-quality covers are multi-layered with a soft inner lining and a weatherproof outer shell. Breathable fabrics repel water and UV rays while letting moisture escape. Cheaper covers may use a single thin layer of fabric; these are lighter on price but less durable and less UV-resistant.
• Fit: Covers come in custom-fit and universal sizes. Custom-fit covers are made exactly for your RV model, for a snug fit. Universal-fit covers fit a range of lengths and use elastic hems or straps to secure them. Always measure your RV’s total length, width, and height (including roof vents and accessories) before choosing a size. A too-loose cover can flap in the wind and tear, while a very tight cover may strain the fabric.
• Weather Resistance: All-season covers have extra layers and vent panels to handle snow, ice, rain, and UV rays. Other covers (often labeled “summer” or “UV”) focus on sun protection and airflow. In harsh winter or heavy rain regions, choose a heavy-duty 4-season cover. In milder climates, a lighter cover may suffice.

Benefits of Using an RV Cover

Whether you’re a full-time traveler or a weekend camper, investing in a high-quality RV cover comes with long-term advantages for your vehicle. A properly fitted, breathable, and weather-resistant RV cover offers more than just cosmetic protection—it can save you thousands in maintenance and repairs over time. Below are the key benefits of using an RV cover:

• Protects Against Sun and Weather: Prolonged sun exposure leads to faded paint, cracked rubber seals, and damaged interiors. A UV-resistant RV cover helps block harmful rays and keeps your RV cooler. It also guards against rain, snow, ice, and hail, minimizing the risk of rust, leaks, and water damage.
• Keeps Your RV Clean: Covers prevent buildup of dust, bird droppings, tree sap, pollen, and other debris that can stain surfaces or clog vents. Less exterior grime means fewer washes and waxes, helping preserve your RV’s paint and finish.
• Deters Pests and Rodents: A snug-fitting RV cover can make it harder for mice, birds, and insects to enter through roof vents or storage bays. This reduces the risk of nests, chewed wires, or infestations during storage periods.
• Reduces Maintenance Costs: By limiting UV exposure and moisture, RV covers reduce wear on seals, paint, roof membranes, and plastic components. Over time, this means fewer repairs and part replacements.
• Preserves Resale Value: A well-maintained, cleaner RV fetches a higher resale price. Buyers will see that your vehicle has been cared for, inside and out, thanks to the added protection a cover provides.

How to Choose the Right RV Cover

Choosing the best RV cover means matching it to your RV, climate, and storage plans. Consider these tips:

• Measure Your RV: Measure the total length, width, and height of your RV (including roof vents or accessories). Pick a cover size slightly larger than your RV to ensure full coverage.
• Material & Durability: For sunny climates, choose fabrics with strong UV protection. In rainy or snowy regions, opt for heavier, water-resistant multilayer covers. Ensure the material is breathable to avoid trapped moisture.
• Fit Type: Decide between custom-fit and universal covers. Custom-fit covers match your RV model exactly for a snug fit. Universal-fit covers cover a range of lengths and use elastic hems or straps to secure them. Always make sure the cover can accommodate any slide-outs or roof accessories you have.
• Features & Access: Look for built-in vent panels and straps to secure the cover. Zippered panels or doors let you reach your RV’s entry or storage compartments without removing the entire cover.
• Brand & Warranty: Check user reviews and pick a reputable brand. A good warranty or satisfaction guarantee shows confidence in the product.

Tips for Proper Use and Maintenance

To get the most out of your RV cover, it’s not just about buying the right one—it’s about using it correctly and caring for it over time. Proper installation and routine maintenance can make a big difference in the longevity of both your RV and the cover itself. Below are essential tips every RV owner should follow to maximize protection and avoid common mistakes.

• Clean and Dry: Always wash your RV before covering it, removing dirt, grime, and tree sap. Make sure the RV is completely dry, as moisture trapped underneath can lead to mildew, corrosion, or surface damage. Never cover a damp vehicle—allow it to air dry fully.
• Install Carefully: Wait for a calm day to install your RV cover. Start from the top of the roof, then gently pull it down over the sides, aligning it front to back. Secure the fit using all available tie-downs, straps, or buckles. Ensure built-in vent flaps align with your roof vents to prevent trapped condensation.
• Remove Snow and Water: After rain or snowfall, use a soft brush or broom to remove any accumulation. Letting snow or water pool on top of the cover may cause stretching, sagging, or even tears, especially in colder climates.
• Clean the Cover Itself: Periodically, take down the cover and clean it with mild soap and lukewarm water. Avoid harsh detergents or machine washing. Rinse thoroughly and allow it to dry completely before refolding and storing. Spot-clean any visible stains immediately to avoid setting.
• Store Properly: Once clean and dry, fold the cover neatly and place it back in its storage bag. Store it in a cool, dry space—away from direct sunlight and moisture. Proper storage helps prevent mold and extends the lifespan of the fabric.

Mistakes to Avoid with RV Covers

• Using Tarps or Non-Breathable Covers: Never substitute a cheap tarp or plastic sheet. Tarps trap moisture, leading to mold and rot. Always use a purpose-made RV cover.
• Poor Fit: An ill-fitting cover (too loose or too tight) can do more harm than good. Loose covers flap and can tear; very tight covers can stress seams. Always secure straps or elastic hems so the cover fits snugly but not overstretched.
• Covering a Dirty or Wet RV: Placing a cover on a dusty, moldy, or wet vehicle traps dirt and moisture underneath. This can scratch paint and cause mold growth. Always clean and dry your RV before covering it.
• Neglecting Tie-Downs: Wind can lift and tear a cover if it’s not secured. Failing to use the provided straps, elastic hems, or anchors is a common mistake. Make sure to anchor the cover properly every time.
• Driving with the Cover On: Never drive your RV while the cover is on. It will block your view and likely fly off or tear, damaging both the cover and your RV.

RV Cover FAQs

Are RV covers waterproof?

Most covers are water-resistant, not fully waterproof. They repel rain but seams can leak. For heavy rain, choose a cover labeled “waterproof”.

How do I measure my RV for a cover?

Measure your RV’s full length (front bumper to rear) and note its width and height (including roof vents or AC). Pick a cover size slightly larger than these measurements for full coverage. For a step-by-step guide with diagrams and pro tips, check out our blog on How to Measure Your RV for an RV Cover.

Can I use a tarp instead of an RV cover?

No. Tarps aren’t breathable and trap moisture, which causes mold and rust. Use a cover made for RVs, which is water-resistant and allows air circulation.

Will an RV cover keep out pests and rodents?

A snug cover blocks most entry points, deterring pests. For extra protection, use repellents (like mothballs) and inspect the RV interior occasionally.

How do I clean an RV cover?

Spot-clean stains (like bird droppings) with mild soap immediately. Hand-wash the cover with gentle detergent, rinse thoroughly, and air-dry before storing.

How long do RV covers last?

A quality cover lasts about 3–5 years. Its lifespan depends on the fabric and exposure to sun or snow. Replace the cover once it shows wear to keep protecting your RV.

Can I drive with my RV cover on?

Never drive with the cover on. It will block your view and likely tear or blow off. Always remove and secure the cover before driving.

Should I cover my RV in winter?

Yes, if parked outdoors. Use a heavy-duty winter cover to protect from snow, ice, and salt. Clear off heavy snow regularly to prevent excess weight and damage.

Will an RV cover protect against hail?

Covers provide minimal hail protection. They may cushion small hail, but large hailstones can still dent or crack the RV. For severe hail, indoor storage is safer.

What features make the best RV covers?

Look for heavy-duty, water-resistant, breathable fabrics. A snug custom fit prevents sagging. Vent panels, strong straps, and zippers are useful. All-season covers often perform best.
