Every RVer plans for campground fees and fuel-but fewer think about what happens inside exterior storage compartments.
Even “sealed” bays aren’t fully airtight. Temperature swings can create condensation, and small gaps around seals may allow moisture in. Over time, that trapped humidity can lead to rust, mold, and corrosion-especially if compartments aren’t opened or checked regularly.
It’s rarely one dramatic event. More often, it’s gradual damage to tools, spare parts, fabrics, or electronics that sit unused for months.
Experienced RVers reduce the risk by:
• Inspecting storage bays regularly
• Using desiccants or moisture absorbers
• Storing sensitive items in sealed plastic bins
• Checking and maintaining compartment seals
Moisture isn’t inevitable-but it is something worth paying attention to. A little prevention goes a long way in protecting the gear you store underneath your RV.
