Are you having nightmares of mold and mildew getting in your RV? 

Mold and mildew aren’t the same things! Both are fungi. Mold tends to be the more health-hazardous of the two. It is darker and fuzzier. Mildew turns into a white, powdery substance.

Mold growth begins with a spore – or more than likely, a few bazillion of them. They’re everywhere. In fact, you’re probably inhaling a few right now. Thank your nose hairs for keeping your lungs clean!
