Annual RV Maintenance Checklist
Quick answer: An annual RV maintenance review should cover the roof and exterior seals, tires and running gear, batteries and electrical systems, plumbing, appliances, HVAC, safety equipment, generator and motorhome chassis when equipped, plus your maintenance records. Annual review does not replace any shorter mileage-, hour- or time-based service interval required by a manufacturer.
An annual RV maintenance checklist gives you one scheduled opportunity to review the entire RV instead of only fixing problems as they appear. It is especially useful before a major travel season or when bringing an RV back into regular use.
This guide applies broadly to motorhomes, travel trailers and fifth wheels, but every RV is different. Use the manuals for your RV, chassis, tires, generator and installed equipment for exact inspection procedures, specifications and service intervals.

Start the annual review with last year’s records
Before inspecting the RV, review what happened during the previous year. The annual check is the best time to catch work that was postponed, repeated WATCH items and service that is approaching by date, mileage or generator hours.
- Review maintenance-log entries and professional service invoices.
- Record current mileage and generator hours.
- List unresolved WATCH and REPAIR items.
- Identify tasks that were postponed or repeated during the year.
- Check whether important tire, battery, generator and component records are still current.
1. Perform a detailed roof and exterior review
The annual inspection is a good time to look more carefully at areas you may only glance at during monthly checks. Use safe access methods and follow the RV manufacturer’s roof-access guidance.
- Inspect accessible roofing material for visible deterioration or damage.
- Review seams and sealant around vents, skylights and other penetrations.
- Inspect windows, doors, trim and exterior compartment openings.
- Look for staining, soft areas, delamination or other signs that deserve further evaluation.
- Check exterior lights, reflectors and visible body components.
Water intrusion deserves attention: If you find unexplained moisture, staining, softness or damaged seals, identify the source before simply covering the area with new sealant. Use materials compatible with your specific RV construction.
2. Review tires, wheels and running gear
Do not base tire decisions on appearance alone. Review the applicable tire and RV manufacturer information along with actual condition and use history.
- Inspect tread and sidewalls for visible damage or unusual wear.
- Review tire identification/history and applicable manufacturer guidance.
- Check wheels for visible damage.
- Inspect the spare and carrier if equipped.
- For towables, review brake, bearing, axle and suspension maintenance requirements.
- For motorhomes, include chassis braking, steering and suspension requirements.
3. Inspect batteries and electrical equipment
- Inspect accessible battery terminals, cables and mounting.
- Review battery condition and charging performance using equipment appropriate to your system.
- Inspect accessible shore-power cords, plugs and adapters for damage or overheating.
- Review converter/charger, inverter and solar equipment for warnings or abnormal behavior when installed.
- Check common 12V and 120V equipment for proper operation.
Electrical faults can create shock and fire hazards. Use qualified service when testing or repair is beyond your knowledge.
4. Review the RV plumbing system
- Inspect accessible water lines, fittings and drains for leakage.
- Check faucets, shower and toilet operation.
- Review water-pump operation.
- Inspect the water-heater area and follow its maintenance instructions.
- Review fresh, gray and black tank systems and required sanitation/maintenance procedures.
- Look for unexplained moisture or odors that could indicate a hidden issue.
5. Operate HVAC and major appliances
Test equipment before a trip where you will depend on it. Follow each appliance manufacturer’s operating and maintenance instructions.
- Air conditioner.
- Furnace.
- Refrigerator.
- Water heater.
- Range/cooktop and other installed cooking equipment.
- Vent fans and accessible filters.
6. Inspect slides, awnings, steps and leveling systems
- Operate slide rooms and inspect visible seals and mechanisms.
- Inspect awning fabric and visible hardware under safe conditions.
- Check entry-step operation and mounting.
- Inspect stabilizers, landing gear or leveling systems.
- Look for visible hydraulic leaks where hydraulic systems are installed.
Use only the lubrication and maintenance procedures specified for the particular mechanism.
7. Review RV safety equipment
- Test smoke alarms according to their instructions.
- Test carbon-monoxide alarms where equipped.
- Test LP-gas alarms where equipped.
- Review manufacturer replacement dates for alarms.
- Inspect the fire extinguisher according to its label and manufacturer guidance.
- Check that emergency exits remain accessible and operable.
8. Review generator service
If your RV has a generator, compare its operating hours and maintenance history with the generator manufacturer’s schedule. Depending on the unit, service may be based on operating hours, elapsed time or both.
Record completed service and the next expected interval in your RV maintenance log.
9. Add motorhome chassis maintenance
Motorhome owners should treat the chassis as a separate maintenance system. The annual RV review is a convenient reminder to check whether any mileage- or time-based chassis service is due.
- Engine oil and filters.
- Transmission/drivetrain requirements.
- Chassis fluids.
- Brakes, steering and suspension.
- Starting battery.
- Belts, hoses and filters where applicable.
- Any dashboard warning or unresolved diagnostic issue.
Do not wait for the annual review if the chassis manufacturer specifies a shorter mileage or time interval. The manufacturer’s schedule takes priority.
10. Add travel trailer and fifth-wheel maintenance
Towable RVs need an annual review of towing-related components in addition to the house systems.
- Hitch/coupler or fifth-wheel components.
- Safety chains where applicable.
- Breakaway system.
- Trailer electrical connector and lights.
- Brakes, bearings, axles and suspension according to manufacturer requirements.
- Landing gear or stabilizers.
11. Review seasonal preparation
Your annual maintenance date may coincide with winterization, storage or spring recommissioning. Keep those procedures separate enough that important climate-specific steps are not buried inside a general annual checklist.
Dedicated RV Winterizing and RV De-Winterizing checklists will cover those seasonal workflows separately.
12. Update your RV maintenance records
Finish the annual review by documenting what happened. This turns a one-day inspection into useful history for future troubleshooting, budgeting and resale.
- Date of inspection/service.
- Mileage and generator hours when relevant.
- Work performed.
- Parts and fluids used.
- Professional service performed.
- Repair costs.
- Unresolved items.
- Next due date, mileage or operating-hour target.
Annual vs. monthly RV maintenance
Monthly maintenance is primarily about catching developing problems during regular use. The annual review is broader: it brings together major systems, service history and longer-term planning.

Annual RV maintenance FAQ
What maintenance should be done annually on an RV?
An annual review commonly includes the roof and exterior, tires/running gear, batteries and electrical systems, plumbing, appliances, HVAC, safety equipment, moving systems and maintenance records. Motorhomes also require chassis maintenance, while towables require attention to towing equipment and running gear.
Is once-a-year RV maintenance enough?
No. Many items need frequent or pre-trip inspection, and some components have manufacturer service intervals based on mileage, operating hours or elapsed time. Annual maintenance is one layer of the overall schedule.
When is the best time to do annual RV maintenance?
Many owners find it convenient before a major travel season or when returning the RV to regular use. The important point is to schedule the review consistently without delaying any manufacturer-required service.
Should I keep receipts from RV maintenance?
Keeping receipts with your maintenance log provides a clearer history of repairs, parts and professional service. That history can be useful for planning, troubleshooting and future resale.
