The Ultimate Caravan & Motorhome Maintenance Checklist

The Ultimate Caravan & Motorhome Maintenance Checklist

Owning a caravan or motorhome gives you the freedom to explore New Zealand whenever the road calls. Whether you're heading to Northland's beaches, the Central Plateau or the deep south, keeping your RV well maintained helps ensure every trip is safe, reliable and enjoyable.

Regular maintenance doesn't just reduce the chance of breakdowns—it can also extend the life of your investment, improve resale value and help avoid costly repairs later.
Here's a practical maintenance checklist every caravan and motorhome owner should follow throughout the year.

Before Every Trip

Taking ten minutes before you leave can save hours of frustration later.

Check:

•    Tyre pressures and tread depth
•    Wheel nuts
•    Exterior lights
•    Indicators and brake lights
•    Mirrors
•    Gas bottles are secure
•    Fresh water level
•    Waste tanks are empty
•    Battery charge
•    Hitch and coupling
•    Safety chains
•    Brake operation
•    Awning is securely locked
•    Roof hatches and windows closed

If towing a caravan, also make sure the tow ball weight is appropriate and your load is evenly distributed.

Check Your Tyres Regularly

Caravan tyres often age before they wear out.

Inspect for:

•    Cracks
•    Bulges
•    Uneven wear
•    Objects embedded in tread
•    Correct inflation

Under-inflated tyres generate excess heat and increase the likelihood of failure.

Even tyres with plenty of tread may need replacing after several years due to age and UV exposure.

Keep Your Water System Clean

Fresh water systems should be cleaned periodically to help reduce the build-up of bacteria, algae and unpleasant odours.

Remember to:

•    Empty fresh water tanks before long-term storage
•    Flush pipework
•    Sanitise tanks when required
•    Inspect hoses and fittings
•    Replace damaged seals

Maintain Your Toilet System

Using quality toilet chemicals helps:

•    Control odours
•    Break down waste
•    Protect seals
•    Improve tank hygiene

Regular cleaning of both the cassette and seals helps extend the life of your toilet system.

Inspect Rubber Seals

Rubber seals protect against:

•    Water leaks
•    Dust
•    Road grime
•    Insects

Check around:

•    Doors
•    Windows
•    Roof hatches
•    Storage lockers

Clean seals regularly and apply a suitable rubber conditioner to help prevent drying and cracking.

Test Your Electrical System

Check:

•    Battery voltage
•    Solar charging (if fitted)
•    Mains charging
•    Internal lights
•    USB outlets
•    12V appliances

Clean battery terminals if corrosion develops.

Check Gas Appliances

Inspect:

•    Gas hoses
•    Regulators
•    Connections

Test:

•    Stove
•    Oven
•    Water heater
•    Fridge
•    Heating system

If you ever smell gas, turn the supply off immediately and have the system inspected before further use.

Service Your Awning

Your awning is exposed to:

•    UV
•    Wind
•    Rain
•    Salt air

Regularly:

•    Clean fabric
•    Lubricate moving joints where recommended
•    Check arms
•    Inspect locking mechanisms
•    Always allow awnings to dry before storing them to reduce the risk of mould.

Lubricate Moving Parts

Apply suitable lubricant to:

•    Corner steadies
•    Door hinges
•    Lock mechanisms
•    Couplings
•    Jockey wheel
•    Stabiliser components

Avoid over-lubricating parts that attract dust.

Check the Roof

Your roof experiences constant exposure to:

•    UV rays
•    Rain
•    Tree debris
•    Bird droppings

Inspect:

•    Sealants
•    Roof vents
•    Solar panel mounts
•    Satellite equipment
•    Air conditioning units

Catching small seal failures early can help prevent expensive water damage.

Store Your Caravan Properly

If storing your RV for several weeks or months:

•    Empty water systems
•    Disconnect batteries if appropriate
•    Clean the interior
•    Remove food
•    Ventilate the interior
•    Use breathable covers where suitable
•    Park on level ground

Proper storage helps protect your caravan or motorhome during New Zealand's changing seasons.

Replace Worn Parts Before They Fail

Many components naturally wear over time.

Common replacement items include:

•    Water hoses
•    Gas fittings
•    Rubber seals
•    Awning accessories
•    Plumbing connectors
•    Corner steadies
•    Lighting
•    Water treatment products
•    Toilet chemicals

Replacing inexpensive items before they fail can help avoid much larger repair bills later.

Keep a Maintenance Log

Recording servicing and maintenance makes it easier to:

•    Track replacement intervals
•    Remember inspections
•    Support resale value
•    Identify recurring issues

A simple notebook or digital spreadsheet works well.

Why Preventative Maintenance Matters

Routine maintenance is one of the easiest ways to protect your investment.

Benefits include:

•    Improved reliability
•    Better road safety
•    Longer component life
•    Reduced repair costs
•    Better fuel efficiency when towing
•    Greater resale value
•    More enjoyable holidays

A little attention throughout the year can provide peace of mind every time you hit the road.

Frequently Asked Questions

How often should I service my caravan?

Most owners should inspect their caravan before every trip and perform a more thorough maintenance check every six to twelve months, depending on usage.

How often should a motorhome be serviced?

In addition to the vehicle manufacturer's servicing schedule, inspect the living area, plumbing, electrical system and appliances at least annually.

How long do caravan tyres last?

Even if the tread looks good, caravan tyres may need replacing after several years due to ageing, UV exposure and weathering. Regular inspections are essential.

Should I empty my fresh water tank before storing my caravan?

Yes. Emptying the tank before storage helps reduce stagnant water, unpleasant odours and the potential for bacterial growth.

How often should I clean my caravan toilet cassette?

The cassette should be emptied whenever practical during use and thoroughly cleaned regularly with suitable waste treatment products.

How do I stop rubber seals from cracking?

Keep seals clean and use a rubber conditioner designed for automotive or RV applications. Regular maintenance helps reduce drying and cracking.

Can I leave my caravan battery connected during storage?

This depends on your battery type and charging setup. Many owners use a quality maintenance charger or disconnect the battery during extended storage.

What should I check before towing a caravan?

Check tyre pressures, wheel nuts, lights, coupling, safety chains, brakes, mirrors, gas bottles, load distribution and that all external lockers, windows and roof hatches are securely closed.

Why is preventative maintenance important for caravans and motorhomes?

Routine maintenance helps improve safety, reduce unexpected breakdowns, extend the life of your RV and minimise expensive repairs over time.
