Whether you’re storing your RV for winter, summer heat, or an extended break between trips, proper preparation makes all the difference. Skipping steps can lead to mold, battery failure, tire damage, leaks, and expensive repairs.
This guide to Preparing Your RV for Storage: A Step-by-Step Checklist walks you through exactly what to do—inside and out—so your RV stays safe, secure, and road-ready.
Why Proper RV Storage Preparation Matters
RVs are complex systems on wheels. They include:
Plumbing systems
Electrical systems
Roofing and sealants
Tires and suspension
Appliances and fuel systems
When left unused, these components can deteriorate quickly without proper care. A few hours of preparation now can save thousands later.
Step 1: Clean the RV Thoroughly
Cleaning isn’t just about appearance—it prevents long-term damage.
Exterior Cleaning
Wash and wax the RV to remove dirt, bugs, and road salt
Clean the roof to prevent buildup and staining
Inspect seals and caulking while washing
Waxing adds an extra protective layer against UV damage.
Interior Cleaning
Remove all food and trash
Vacuum floors and upholstery
Wipe down countertops and cabinets
Defrost and clean the refrigerator
Even small crumbs can attract pests.
Step 2: Empty & Protect the Plumbing System
If storing long-term, plumbing prep is critical.
For Cold Climates
Drain fresh water tank
Drain water heater
Bypass water heater
Add RV antifreeze to lines
For Warm Climates
Drain tanks to prevent stagnation
Ensure gray and black tanks are empty and cleaned
Water left sitting can cause odors, bacteria growth, and cracked pipes.
Step 3: Protect the Battery
Battery neglect is one of the most common storage mistakes.
Battery Checklist
Disconnect the battery
Fully charge before storage
Use a trickle charger if available
Store in a cool, dry place if removed
A dead battery can shorten lifespan permanently.
Step 4: Stabilize the Fuel System
Fuel degrades over time.
Gas-Powered RVs
Add fuel stabilizer
Fill tank to reduce condensation
Run engine briefly after adding stabilizer
Diesel RVs
Add diesel stabilizer
Consider a biocide if storing long-term
This prevents fuel system clogs and costly repairs.
Step 5: Inspect & Seal the Exterior
Moisture intrusion causes major damage.
What to Inspect
Roof seams
Slide-out seals
Window seals
Storage compartment gaskets
Reseal cracks immediately to prevent leaks.
Step 6: Protect Tires & Suspension
Tires suffer when sitting idle.
Tire Protection Tips
Inflate to recommended PSI
Use tire covers to block UV rays
Move RV slightly every few weeks if possible
Consider leveling blocks to reduce weight pressure
Tire replacement is expensive—protect them.
Step 7: Control Moisture & Ventilation
Trapped moisture leads to mold and mildew.
Moisture Control Checklist
Use moisture absorbers inside
Install vent covers
Leave cabinets slightly open
Crack windows slightly if safe
Airflow is key to preventing musty odors.
Step 8: Choose the Right Storage Type
Where you store matters just as much as preparation.
Outdoor Storage
Most affordable
Requires high-quality cover
Covered Storage
Shields from UV and hail
Reduces long-term wear
Indoor Storage
Maximum protection
Best for long-term or high-value RVs
Match storage type to climate and budget.
Step 9: Secure Your RV
Security prevents theft and vandalism.
Lock all doors and compartments
Remove valuables
Use steering wheel or hitch locks
Verify gated or monitored storage facility
Peace of mind is priceless.
