Should I run a dehumidifier in my RV during storage?

Yes — moisture damage is the #1 issue for stored RVs. A renewable desiccant (Eva-Dry) works when unplugged, or connect a small Peltier unit to a solar panel for continuous protection.

What humidity level should I target in an RV?

40-50% relative humidity prevents mold and condensation without making the air uncomfortably dry. In humid coastal areas, maintaining 50% may require a compressor-based unit.
