- Solar Panels: Keep panels clean for maximum charging efficiency. Inspect wiring for damage.
- Have your brakes inspected annually. This includes checking pads, rotors/drums, calipers, and fluid. For towable RVs with electric brakes, ensure the magnets and shoes are in good condition and adjust as needed.
Your generator, whether a built-in Cummins Onan or a portable unit, is vital for off-grid power. Run it regularly (at least 30 minutes monthly with a load) to keep components lubricated. Follow its specific maintenance schedule for oil changes, spark plug replacement, and filter changes.
These systems are what make your RV feel like home. Neglecting them can lead to unpleasant and costly issues.
- Freshwater Tank: Sanitize annually using a bleach solution (e.g., 1/4 cup bleach per 15 gallons of water).
- Water Heater: Drain and flush annually to remove sediment. Inspect and replace the anode rod (if applicable) every 1-2 years to prevent corrosion.
- Water Pump: Check for proper operation and leaks.
- Black/Gray Tanks: Flush thoroughly after each use. Use tank treatments to break down waste and control odors. Maintain valve lubricity.
- Leak Checks: Regularly inspect under sinks, around toilets, shower connections, and the water heater for any signs of leaks.
- A/C Filters: Clean or replace your rooftop A/C filters regularly, especially before summer trips.
- Furnace: Have your furnace inspected annually by a qualified technician, checking the burner assembly, exhaust, and safety cut-offs. Clean any accessible air intakes.
- Roof Vents & Fans: Keep clean and ensure smooth operation. Check seals around vents.
- Refrigerator: Keep coils clean for optimal efficiency. Check door seals for integrity. Defrost regularly.
- Microwave/Oven/Stove: Keep clean. Check propane connections for stoves/ovens for leaks.
- Have a professional conduct a propane leak test annually. Check hoses and regulator for cracks or wear. Ensure tanks are securely mounted. Always transport and store tanks upright.
The exterior of your RV protects everything inside. Regular inspection and care are critical to prevent water damage and structural issues.
Roof Maintenance
The roof is your RV's primary defense against the elements. Inspect it thoroughly at least twice a year, and after any severe weather.
- Inspection: Look for cracks, tears, punctures, or separation in the membrane or sealant around vents, skylights, and AC units. 2026 models often use more durable TPO or fiberglass roofs, but seals are always vulnerable.
- Sealant: Reapply self-leveling or non-sagging sealants as needed. Dicor or Eternabond tape are common choices for repairs.
- Cleaning: Wash the roof regularly to prevent mold, mildew, and black streaks. Use RV-specific roof cleaners.
Inspect all seals and caulking around windows, doors, cargo bays, and body seams. Even a small crack can allow water intrusion, leading to costly delamination or rot. Re-caulk with marine-grade or RV-specific sealants as soon as any deterioration is noted.
Wash your RV regularly to remove dirt, bugs, and road grime. Apply a UV protectant wax or sealant every 6-12 months to protect the finish, especially on full-body paint Class A coaches like the Newmar Dutch Star or laminated fiberglass towables like a Grand Design Imagine.
Keep your awning fabric clean and dry before retracting to prevent mold and mildew. Inspect for tears or damage. Lubricate pivot points and arms as per the manufacturer’s instructions.
Proper seasonal prep is non-negotiable for protecting your RV during long periods of inactivity.
If you live in a region with freezing temperatures, winterizing is crucial. This involves:
- Draining all freshwater lines, hot water heater, and holding tanks.
- Bypassing the hot water heater.
- Pumping non-toxic RV antifreeze through the plumbing system.
- Cleaning out the refrigerator/freezer and leaving doors ajar.
- Removing and storing batteries in a warm place, or ensuring they are fully charged and maintained with a trickle charger.
For those storing in extreme heat, ensure all vents are clear, and consider using a dehumidifier if moisture is an issue. Fully charge and maintain batteries. Protect tires from UV rays.
Seal all potential entry points. Remove all food items. Use pest deterrents like dryer sheets or natural repellents.
Inflate tires to their maximum recommended PSI during storage. Cover them to protect from UV degradation, which can cause cracking and premature failure.
