Tips for Buying an RV Cover

1. Get the Right Size

RV covers come in a wide range of sizes to accommodate different types—from Class A motorhomes to travel trailers and fifth wheels. It's crucial to measure your RV's length, width, and height accurately, including accessories like ladders, AC units, and satellite dishes. A custom-fit or semi-custom cover is always best to prevent sagging and to ensure a snug fit that doesn't flap in the wind. A poorly fitted cover can lead to tears or scuffing of the RV’s surface over time.

2. Consider the Cost

High-quality RV covers can be a bit pricey, but they are a worthwhile investment compared to the cost of exterior repairs or repainting. Look for multi-layered covers with UV protection, waterproofing, and breathability. Cheaper covers may lack these critical features and wear out quickly. Watch for deals online, particularly during the off-season, and be sure to review warranty options as part of your decision.

3. Waterproof vs. Weatherproof Covers

When choosing an RV cover, one important distinction to understand is the difference between waterproof and weatherproof materials. Both offer protection, but in different ways.

Waterproof covers are designed to completely block water from passing through. This might seem ideal, especially in areas with heavy rain or snow, but fully waterproof covers can trap moisture beneath them if the RV isn't completely dry when covered. This can lead to mold, mildew, and damage to the paint or seals over time. Additionally, waterproof covers often lack breathability, which means condensation may accumulate underneath without a way to escape.

Weatherproof covers, on the other hand, are water-resistant and breathable. They repel most moisture while allowing airflow to reduce condensation. This type of cover is excellent for fluctuating climates and long-term outdoor storage. Weatherproof covers often feature vent panels and multi-layer fabrics that offer protection from UV rays, wind, dust, and debris—making them more versatile in varying conditions.

Pros of Waterproof Covers: Maximum water resistance, better short-term protection in downpours, and ideal for temporary outdoor use.
Cons: Poor breathability, potential for trapped moisture, and not ideal for long-term storage.

Pros of Weatherproof Covers: Breathable, balanced protection from multiple elements, reduces condensation risks, and great for long-term use.
Cons: Not 100% water-tight, may allow minimal seepage in extreme conditions, and usually more expensive.

For most RV owners, a weatherproof cover provides the best year-round balance of protection and ventilation. Choose according to your storage location and climate conditions.

4. Pick the Right Color

Just like with cars, lighter-colored RV covers reflect sunlight and help keep the interior cool, which is especially important in warmer climates. Darker covers can absorb heat, which may damage exterior seals over time. However, some dark-colored covers are treated to resist UV damage and fading. Choose a color that suits your climate and ensures your RV remains protected during storage.

5. How Often Will You Use It?

Are you planning to store your RV seasonally, or will you cover it only during extreme weather? For seasonal use, a heavy-duty cover with secure straps and reinforced corners is ideal. It can remain in place for months without degrading. If you plan to cover and uncover your RV frequently, choose a model that is easy to install and remove, possibly with zippered access panels for maintenance without taking off the entire cover.

Tips for Maintaining Your RV Cover

1. Proper Installation

Before installing the RV cover, make sure your vehicle is clean and completely dry. Dirt and moisture trapped beneath the cover can cause scratches and promote mold growth. Always install on a calm day and follow the manufacturer's instructions. Start at the front or back and roll the cover evenly across the roof before securing the sides. Use provided straps and buckles to anchor the cover securely to prevent wind damage.

2. Machine Washing

Not all RV covers can be machine washed due to their size and weight. If your cover is machine washable, use a commercial-size washer without a central agitator. Wash with cold or lukewarm water using mild detergent and rinse thoroughly. Never use bleach or fabric softener, as these can weaken the cover’s protective coating. Always air dry completely before storing.

3. Hand Washing

Hand washing is often the best and most practical option. Use a soft brush or sponge with mild soap and water to scrub the cover while it's still on the RV. Be sure to rinse thoroughly to avoid residue buildup, and don’t forget to wash both the top and underside of the cover. Let it dry completely before folding and storing.

4. Spot Cleaning Bird Droppings

Bird droppings are acidic and can deteriorate both your cover and RV finish if left unattended. Use a mixture of water and vinegar or mild soap to clean the area as soon as possible. Rinse well and allow it to dry naturally. Regular spot cleaning can significantly extend the life of your cover.

5. Winter Storage

In freezing temperatures, RV covers can become stiff and may even freeze to the vehicle if moisture is present. Never try to rip a frozen cover off your RV. Instead, gently pour warm water over the area and wait until it loosens. Always ensure your RV is dry before covering, and use covers rated for winter storage with waterproof and breathable properties.

6. Wind Resistance

High winds are one of the biggest threats to your RV cover. Ensure your cover has built-in tension panels, buckles, and adjustable straps. Adding additional tie-down ropes or using wheel anchors can also help secure the cover in extreme conditions. A tight fit minimizes movement and prevents damage from flapping fabric.

7. Proper Storage of the Cover

After use, let your cover dry thoroughly before storing it. Fold it neatly and place it in the original carrying bag or a dry storage container. Keep it in a temperature-controlled area away from direct sunlight and moisture. Proper storage helps maintain fabric integrity and keeps the cover clean and ready for the next use.
