Every RV owner knows a water leak sounds the death knell. But did you know water can ruin your camper without ever leaking inside??

Meet condensation. Condensation sucks. Condensation can:

• Stain your wallpaper
• Grow mildew on your clothes
• Funk up your RV with a wet-newspaper-y smell
• Disintegrate plywood paneling
• Soak into your subfloor
• Corrode aluminum and rust steel parts
• Grow mold inside your walls!
