The Essential End-of-Season Storage Inspection Checklist
As camping season winds down and the cool weather rolls in, it’s time to prepare your rig for its winter hibernation. Taking an extra hour or two to conduct a thorough pre-storage inspection now will save you hundreds—or even thousands—of dollars in unexpected repair costs come spring.
Before you lock up and walk away, use this checklist to ensure your RV is completely protected during the off-season.
1. Inspect the Exterior Seals and Roof

Water intrusion is an RV’s worst nightmare, especially during freezing winter months when trapped water expands and creates massive leaks.
- Roof Membrane: Inspect for cracks, tears, or soft spots.
- Lap Sealant: Check the sealant around vents, skylights, AC units, and edge molding. Reseal any areas showing cracking, shrinking, or lifting.
- Window & Door Seals: Inspect the caulking around all windows, baggage doors, and exterior body seams.
- Slideout Sweeps: Check the slideout rubber seals for tears, dry rot, or cracks. Clean them thoroughly and apply a rubber seal conditioner to keep them pliable.
2. Thoroughly Winterize the Plumbing
Frozen pipes are the single most common cause of springtime RV repairs.

- Drain Tanks: Completely drain your fresh water tank, grey water tank, and black water tank. Flush the black tank thoroughly to prevent buildup.
- Bypass & Drain the Water Heater: Pull the drain plug/anode rod to empty the tank. Never add antifreeze directly to your water heater.
- Run RV Antifreeze: Blow out the lines with compressed air (under 50 PSI) or pump non-toxic RV antifreeze through all hot and cold lines, including exterior showers, city water connections, and toilet valves. Don’t forget to pour a cup into each sink and shower drain trap!
3. Protect Electrical Systems & Batteries
Parasitic loads (like LP detectors and stereo clocks) will drain an RV battery in just a few weeks.

- Disconnect Batteries: Fully charge your house and chassis batteries, turn off the main disconnect switch, or physically disconnect the negative terminal.
- Cold Storage Tip: If you live in a region with freezing temperatures, store your fully charged batteries indoors on a wooden workbench or shelf.
- Solar & Generators: Clean your solar panels. If you have an onboard generator, run it under load according to the manufacturer’s instructions, add a fuel stabilizer, and change the oil.
4. Pest-Proof the Interior and Exterior
Mice, insects, and squirrels look for warm, sheltered spots to nest during cold months.
- Deep Clean: Remove all food items, including canned goods, dry boxed goods, and spices. Vacuum up every crumb in drawers, under seats, and behind appliances.
- Block Entry Points: Inspect the underside of your RV. Use stainless steel wool or expandable foam to plug any gaps around wire penetrations, plumbing pipes, or frame openings.
- Cover Vents: Install wire mesh screens over furnace exhaust vents, water heater access panels, and fridge vents to keep mud daubers and mice out.
5. Prevent Mold and Mildew
Trapped moisture leads to stubborn mildew and foul odors.

- Clean & Defrost: Thoroughly clean the refrigerator and freezer. Prop the doors wide open using door stays to prevent mold growth.
- Moisture Absorbers: Place tub-style moisture absorbers (like DampRid) in the center of the cabin, the bathroom, and deep closets.
- Window Covers: Pull shades down to block UV rays from fading interior fabrics, but leave a tiny gap to encourage minimal air circulation if you aren’t using a full breathable RV cover.
6. Tire & Chassis Care
Leaving heavy weight on static rubber for months can cause flat spots and sidewall cracking.
- Inflate to Max PSI: Inflate all tires to the cold PSI rating listed on your RV’s sidewall certification label.
- Tire Covers: Install UV-blocking tire covers to prevent sun damage.
- Leveling & Blocks: If parking on dirt or grass, park the tires on wood planks, rubber mats, or leveling blocks to keep the tires out of damp soil. Keep hydraulic jacks clean and greased if left extended, or store them fully retracted.
