A motorhome is one of the most significant investments a recreational vehicle owner will make. Protecting it from the elements when not in use is not optional — it is essential. A purpose-built RV cover shields your vehicle from UV radiation, rain, wind, dust, bird droppings, leaves, and other environmental pollutants that silently degrade your motorhome's exterior over time.
Indoor vs. Outdoor RV Covers: Know the Difference
| Feature | Indoor RV Cover | Outdoor RV Cover |
|---|---|---|
| Purpose | Dust, scratches, light moisture | Full weather — rain, UV, wind, snow |
| Material | Soft, lightweight fabric | Heavy-duty Oxford / multi-layer non-woven fabric |
| Durability | Moderate | High — designed for long-term storage |
| Recommended for | Garage or covered parking | Driveway, campsite, open-air storage |
1. Material: The Most Important Factor
- Oxford fabric (300D): The industry standard for outdoor RV covers, valued for its balance of weight and durability.
- Multi-layer non-woven fabric (4-ply / 5-ply construction): Layered non-woven fabric combining a weather-resistant outer layer with a softer inner layer against the RV's surface — built for consistent, long-term outdoor protection.
A motorhome that only gets used a few weeks a year still needs to be protected the rest of the time. RVIA's own 2025 Go RVing RV Owner Demographic Profile found that the median RV is used just 30 days a year — meaning most RVs spend the remaining 335 days or so parked and exposed to the elements, which is exactly when UV and moisture damage does the most cumulative harm.
Key properties to confirm before purchasing:
- UV-resistant, anti-aging fabric treatment
- Mold and mildew resistant treatment
- Tear-resistant reinforcement at stress points (corners, ventilation panels)
Oxford Fabric (300D)
- Tightly woven, high-density weave
- Strong tear and abrasion resistance
- Best for high-wear, high-traffic storage spots
Multi-Layer Non-Woven Fabric
- Layered construction (4-ply / 5-ply)
- Weather-resistant outer layer, softer inner layer
- Lightweight option for long-term outdoor storage
2. Size: Measure Before You Buy
How to measure your RV for the right cover size:
- Measure overall length — from the very front bumper to the rear bumper (including any attachments like bike racks or spare tires)
- Measure maximum width — at the widest point, including slide-outs if extended
- Measure overall height — from the ground to the highest point (roof-mounted AC unit, antennas, etc.)
3. Key Features to Look For
Reinforced Straps and Buckles
High-quality covers include adjustable straps that run underneath the vehicle to anchor the cover against wind lift. Look for heavy-duty buckles — cheap plastic clips break in cold weather.
Zippered Access Panels
Some covers include zipper panels at doors and compartments so you can access your RV without removing the entire cover.
Vents and Breathability Panels
Even waterproof covers need ventilation. Built-in air vents prevent wind-induced ballooning, reduce condensation buildup, and relieve pressure in high-wind conditions. The National Weather Service notes that sustained winds of 40–50 mph can cause isolated wind damage — a properly anchored RV cover with a robust strap system is meaningful protection at those wind speeds.
