Keeping your caravan in top condition isn’t just about avoiding breakdowns on the road. It’s about safety, protecting your investment, and ensuring every trip goes to plan. But with dozens of components to check and different maintenance intervals to remember, it’s easy to let things slide or wonder if you’re doing enough.
The reality is that caravan maintenance follows predictable patterns. Some checks need doing before every trip, others can wait months or even years. The trick is knowing what falls into which category and building a system that actually works for your travel style.
This maintenance schedule breaks down exactly what to check and when, from daily walk-arounds to annual overhauls. Whether you’re mechanically minded or prefer to delegate the technical stuff, you’ll know what needs attention and when to seek professional help.
Before Every Trip (Pre-Departure Checklist)
These checks take 15-30 minutes but prevent 90% of roadside dramas. Do them every single time, even for weekend trips.
Safety Systems
- Tyres: Check pressure (including spare), look for cuts, bulges, or excessive wear
- Wheel nuts: Quick visual check they’re all present and properly seated
- Breakaway cable: Attached to tow vehicle, not dragging
- Safety chains: Crossed under drawbar, not twisted or damaged
- Coupling and jockey wheel: Properly engaged, jockey wheel fully raised
- Lights: All brake, indicator, and marker lights working
Load and Balance
- Weight distribution: Heavy items low and over axles
- External storage: Bikes, jerry cans, spare parts properly secured
- Awning and annexe: Properly stowed, zips closed
- Water tanks: Empty or calculate weight into total load
Quick Interior Check
- All cupboards and doors: Latched properly
- Gas bottle: Turned off at bottle, tap, and appliances
- Fridge: Secured for travel, set to 12V or gas
- Loose items: Secured in drawers or packed away
Create a laminated checklist and keep it in your tow vehicle’s glovebox. Tick off each item as you go – even experienced travellers miss obvious things when rushed.
Monthly Maintenance
Monthly checks catch problems before they become expensive. If you’re travelling continuously, do these whenever you’re staying put for more than a week.
Running Gear
- Tyre condition: Detailed inspection for wear patterns, cracking, or embedded objects
- Wheel bearings: Check for play by rocking wheels, listen for grinding noises
- Brake system: Visual inspection of electric brake controller, brake shoes if accessible
- Suspension: Check leaf springs, shock absorbers, and mounting bolts
Electrical Systems
- Battery voltage: Test 12V system with multimeter (12.6V+ when resting)
- Solar panels: Clean surface, check connections aren’t loose
- Anderson plug: Clean contacts, ensure tight connection
- 240V system: Test all outlets, check RCD trips correctly
Water and Waste
- Fresh water system: Sanitise tanks, check pump operation and pressure
- Grey water: Clean sensors, check valve operation
- Black water: If fitted, check seals and sensors
- Hot water service: Check anode (if accessible), test pressure relief valve
Every 3 Months
Quarterly maintenance catches wear before it becomes dangerous. Time these checks with seasonal changes or every 10,000-15,000km of travel.
Structural Inspection
- Drawbar and chassis: Look for stress cracks, particularly around welds
- Floor and walls: Check for soft spots indicating water damage
- External seals: Inspect all door, window, and vent seals
- Roof condition: Check membrane, clean gutters, test drainage
Appliances
- Gas system: Leak test all connections with soapy water
- Fridge: Clean condenser coils, check door seals
- Air conditioner: Clean filters, check drain operation
- Range hood and fans: Clean and lubricate if required
External Components
- Awning: Clean fabric, lubricate arms, check tension
- Steps: Check mounting and operation
- Stabiliser legs: Lubricate winding mechanism, check for damage
- External shower: Test operation, check for leaks
Every 6 Months (Seasonal Service)
Seasonal services align with major temperature changes and are perfect for addressing components that see heavy use. Many travellers time these with their “dry season” and “wet season” preparations.
Deep Clean and Inspection
- Thorough wash: Including undercarriage to remove salt and dirt
- Wax and polish: Protect fibreglass and paint from UV damage
- Interior deep clean: Including air vents, under cushions, and storage areas
- Pest inspection: Check for rodent damage, particularly wiring
Lubrication Schedule
- Coupling mechanism: Clean and grease per manufacturer specs
- Handbrake: Adjust cable tension, lubricate mechanism
- Wind-up legs: Grease winding mechanism and pivot points
- Door and window hardware: Lubricate hinges and latches
System Performance Tests
- Generator: Service and load test under typical conditions
- Inverter: Test under full load, check cooling fans
- Battery bank: Individual cell voltage test, equalisation charge
- Water pump: Performance test, check pressure tank
Use the seasonal service as an opportunity to reorganise storage and rotate emergency supplies. Check expiry dates on first aid kits, fire extinguishers, and food stores while you’re at it.
Annual Maintenance
Annual maintenance is where you address the big-ticket items that keep your caravan roadworthy and valuable. Many of these tasks require professional service.
Professional Services
- Wheel bearing service: Remove, inspect, repack, and adjust bearings
- Brake inspection: Electric brake adjustment, magnet and shoe inspection
- Gas compliance certificate: Required in some states, good practice everywhere
- Electrical safety inspection: 240V system testing and certification
Major Component Service
- Hot water service: Replace anode, descale system if required
- Air conditioner: Professional service including refrigerant levels
- Toilet system: Complete overhaul of cassette or black tank system
- Battery bank: Capacity test, replace failing batteries
Structural Assessment
- Professional inspection: Particularly for vans over 10 years old
- Insurance photos: Document condition for insurance purposes
- Weight check: Confirm loaded weights haven’t crept up over time
- Compliance plate verification: Ensure modifications haven’t exceeded limits
Every 2-5 Years (Major Components)
These are the big-ticket maintenance items that keep your caravan safe and retain its value. Plan and budget for these well in advance.
2-Year Items
- Tyres: Replace regardless of tread depth due to UV and age degradation
- Battery bank: AGM batteries typically need replacement every 3-4 years
- Water tank sanitisation: Professional clean if you’ve had algae issues
3-5 Year Items
- Roof membrane: Professional inspection and potential replacement
- All external seals: Remove and replace door, window, and vent seals
- Solar panel replacement: Efficiency degrades over time
- Awning fabric: Replace if showing UV damage or tears
5+ Year Items
- Hot water service: Complete replacement of unit
- Air conditioner: Major overhaul or replacement
- Inverter/charger: Technology improvements may justify upgrade
- Complete rewire: For older vans with suspect wiring
Never skip tyre replacement based on tread depth alone. Caravan tyres deteriorate from UV exposure and age even with minimal use. Replace every 2 years maximum for safety.
Long-Term Storage Preparation
If you’re storing your caravan for more than 3 months, these steps prevent expensive damage from moisture, pests, and component degradation.
Pre-Storage Tasks
- Deep clean: Remove all food, clean all surfaces, empty all tanks
- Battery maintenance: Remove batteries or connect maintenance charger
- Tyre care: Inflate to maximum pressure, consider tyre covers
- Pest prevention: Seal all vents and openings, use appropriate deterrents
During Storage
- Monthly inspection: Check for pests, moisture, and tyre pressure
- Battery maintenance: Monthly charge if not on maintenance charger
- Ventilation: Open vents on dry days to prevent condensation
- Movement: Move caravan slightly to prevent flat spots on tyres
Pre-Use Preparation
- Full system check: Test all electrical, gas, and water systems
- Safety inspection: Lights, brakes, coupling, and safety chains
- Fresh supplies: Replace expired items in first aid and emergency kits
- Documentation: Check insurance and registration are current
Which Schedule Should You Follow?
The right maintenance schedule depends on your travel intensity, technical skills, and budget. Here’s how to match the schedule to your situation.
| Travel Style | Pre-Trip | Monthly | Quarterly | Annual | Professional Service |
|---|---|---|---|---|---|
| Full-Time Big Lappers Most Common | Always | Every month | Every 3 months | Once per year | Every 6 months |
| Weekend Warriors | Always | Every 3 months | Every 6 months | Once per year | Once per year |
| Long Holiday Travellers | Always | Before long trips | Every 6 months | Once per year | Once per year |
| Occasional Users | Always | Before each trip | Before major trips | Based on age/condition | Every 2 years |
Full-Time Travellers
You’re putting serious kilometres on your van and using all systems heavily. Stick to the aggressive schedule above, but spread the quarterly tasks across the three months to avoid massive service bills.
The monthly checks become critical because you’re often in remote areas where breakdown assistance is limited. Consider carrying more spare parts and learning basic repairs.
Weekend Warriors
Your caravan sees regular use but not continuous stress. You can stretch some intervals but never compromise on safety items like tyres, brakes, and coupling components.
Focus your efforts on the systems you use most. If you free camp regularly, prioritise battery and solar maintenance. If you’re mostly in caravan parks, focus on appliances and comfort systems.
Occasional Users
Storage-related problems become your biggest enemy. Moisture, pests, and component degradation from non-use cause more issues than wear from travel.
Never skip the pre-trip checklist, regardless of how long it’s been since you last used the van. Systems can fail during storage, and safety components need verification every time.
- Pre-trip safety checks are non-negotiable regardless of your travel frequency
- Monthly maintenance prevents 90% of expensive breakdowns and safety issues
- Professional services every 6-12 months maintain warranty and insurance coverage
- Replace tyres every 2 years and major components every 3-5 years based on age, not just condition
- Adjust maintenance frequency based on your usage but never skip safety-critical items
- Storage requires its own maintenance schedule to prevent pest and moisture damage
