Do RV Covers Cause Mold? - The Truth About RV Protection And Breathability
If you've ever covered your RV and then discovered a musty smell or mold stains, you're not alone. Many RV owners worry that RV covers cause mold, but is that true?
In reality, RV covers don't cause mold if used correctly—mold forms due to trapped moisture and lack of ventilation, not the cover itself.
In this guide, we'll explain why mold can form under RV covers, how to prevent it, and why using a breathable, waterproof cover like the BullsArmor RV Cover is the smartest way to protect your investment year-round.

Why People Think RV Covers Cause Mold
It's a common misconception that RV covers cause mold. The truth is, the wrong type of cover can trap moisture, leading to condensation buildup, especially during rainy or humid seasons.
Typical causes of mold complaints include:
- Using cheap, non-breathable tarps that retain moisture
- Covering the RV while it's still damp from washing or rain
- Lack of ventilation during long storage periods
While these problems can lead to mold, a high-quality RV cover like the one from BullsArmor is designed to prevent moisture problems, not cause them.
What Actually Causes Mold Under RV Covers
Mold and mildew develop when moisture is trapped in a dark, warm space with poor ventilation, conditions often found under low-quality RV covers.
Common mold triggers include:
- Non-breathable materials: Vinyl or plastic tarps trap condensation.
- Temperature changes: Temperature fluctuations between day and night cause condensation under covers.
- Dirty surfaces: Dust and organic debris left in the RV encourage mold growth.
- Poor ventilation: No vents or air channels for moisture to escape.
Pro tip: Mold doesn't form because of a cover, but because of moisture without ventilation.
How to Prevent Mold Under Your RV Cover
How to Keep Your RV Mold-Free During Long-Term Storage:
1. Choose a Breathable Cover
Use a multi-layer, breathable cover like the BullsArmor All-Weather RV Cover, which allows water vapor to escape and rain to enter.
- Waterproof Exterior Coating
- Vents for increased air circulation
- UV- and mold-resistant coating
2. Clean and Dry Your RV Before Covering
Wash and dry your RV thoroughly before covering it. Any moisture or dirt can create mold growth.
3. Ventilate Your RV
Leave interior closet doors open and use moisture absorbers (such as DampRid or silica gel pads) inside to balance the humidity.
4. Inspect Regularly
Check your RV cover every few weeks during storage. Brush off any debris and make sure the fabric remains snug but breathable.
5. Store in a dry, shaded area
Avoid storing under trees or near sprinklers, where excessive moisture can accumulate.
