Find and fix sources of water
Inspect roof seams, windows, vents, exterior doors, and plumbing connections for signs of leaks. Repair damage using products approved for the RV’s materials. If you notice soft walls, persistent dampness, or a musty smell, investigate before closing the RV for winter.
Clean and dry the interior
Remove food and rubbish, wipe surfaces, and let damp fabrics dry completely. Check cupboards and storage compartments for hidden spills. Cleanliness reduces odours and makes it easier to spot new problems.
Manage ventilation carefully
Follow the RV manufacturer’s recommendations for ventilation during storage. Moisture-control products may help in some situations, but they are not a substitute for repairing leaks or managing airflow.
Protect belongings
Store dry linens and clothing in a clean, dry location if practical. Avoid packing items tightly against exterior walls where condensation may develop. Leave enough space to inspect the interior when you return.
Check the RV periodically
If storage arrangements permit, inspect after major weather changes. Look for water entry, damaged covers, pests, or unusual odours. Check that vents and openings remain secure.
Combine moisture care with winterization
Water-system protection, battery care, and moisture management are separate tasks. Use the manufacturer’s instructions for each system and seek professional help if unsure.
Every RV and campground has its own requirements. Check your owner’s manual, current local guidance, and resort policies before making safety, maintenance, or booking decisions.
