Annual Caravan Service: What To Expect & What It Costs

Getting your caravan serviced annually isn’t just about ticking a maintenance box. It’s about preventing the kind of expensive failures that can derail your Big Lap halfway around Australia. A blown bearing in the middle of the Nullarbor costs a lot more than a routine service back home.

Most caravan manufacturers require annual servicing to maintain your warranty, but even if your van is out of warranty, that yearly check-up can save you thousands in repairs and weeks of downtime. Here’s exactly what happens during an annual service, what you’ll pay, and why it’s worth every dollar.

What Is An Annual Caravan Service?

An annual caravan service is a comprehensive health check of your entire van, from the chassis and running gear through to the gas, electrical, and water systems. Think of it like a roadworthy inspection combined with a home maintenance check.

The service covers three main areas: safety systems (brakes, tyres, gas, electrical), structural integrity (chassis, drawbar, body), and comfort systems (water pumps, appliances, seals). A good technician will also check for any recalls or manufacturer updates that affect your specific van.

Most caravan manufacturers require annual servicing for the first few years to maintain warranty coverage. After that, it becomes your choice, but the complexity of modern caravans makes professional servicing increasingly valuable. Today’s vans have sophisticated electronics, multiple gas appliances, and intricate water systems that require specialised knowledge to service properly.

The Complete Service Checklist

A thorough annual service should cover these key areas. If your service provider skips any of these items, you’re not getting full value.

Running Gear & Chassis

The technician will inspect your wheel bearings, either by removing the wheels or using diagnostic tools to check for play and heat buildup. They’ll examine the brake system, including brake shoes or pads, brake fluid levels, and the electric brake controller calibration. The suspension gets a full inspection for worn bushings, cracked springs, or leaking shock absorbers.

Tyre condition and pressure get checked, along with wheel alignment if your van has been pulling to one side. The chassis itself is inspected for cracks, corrosion, or damage, particularly around stress points like the A-frame and axle mounts.

Gas System

All gas connections, regulators, and appliances get pressure tested for leaks. This includes the hot water system, cooktop, oven, heating, and any external gas points. The technician will check gas bottle connections, verify regulator operation, and test all pilot lights and ignition systems.

Gas system servicing also includes checking flue terminals are clear and properly sealed, and that all gas appliances are venting correctly. This is critical safety work that prevents carbon monoxide issues.

Electrical Systems

The 12V system gets a comprehensive check, including battery condition and charging rates from both the vehicle and solar panels. All lights, pumps, and accessories are tested for proper operation. The 240V system is tested for safety, including RCD operation and earth continuity.

Modern caravans often have complex monitoring systems, inverters, and battery management systems that require specific diagnostic tools to service properly. The technician should also check all external connections like the Anderson plug and 12-pin connector.

Water System

The entire water system gets flushed and sanitised, including fresh water tanks, grey water systems, and all plumbing connections. The water pump is tested for pressure and flow rate, and all taps and fittings are checked for leaks.

Hot water systems get particular attention, with anode replacement (if fitted), pressure relief valve testing, and thorough flushing to remove sediment buildup. The technician should also check all external water points and ensure dump valve seals are working properly.

Body & Seals

All external seals around windows, doors, roof vents, and access hatches get inspected and resealed if necessary. The technician will check for any signs of water ingress, which can cause expensive structural damage if left unchecked.

Door and window operations are tested, along with all external storage compartments and their locking mechanisms. The roof should be thoroughly inspected for damage, especially if you’ve been travelling on unsealed roads.

What An Annual Service Costs

Annual caravan services typically cost between $400-800 depending on your van’s size, age, and complexity. Here’s what drives the price differences.

Basic Service ($400-500)

A basic service covers the essential safety checks: brakes, bearings, gas system pressure test, basic electrical checks, and visual inspection of seals and structure. This level of service is suitable for newer vans under warranty where you’re mainly ticking the manufacturer’s requirements.

Comprehensive Service ($600-800)

A comprehensive service includes everything in the basic service plus: complete wheel bearing repack, brake adjustment or replacement, gas appliance servicing, battery load testing, water system sanitisation, and detailed seal inspection with minor repairs.

Larger vans with slide-outs, multiple air conditioners, or complex electrical systems like lithium batteries and inverters will be at the higher end of this range.

Additional Costs

Services typically cover labour and basic consumables like bearing grease and brake adjustments. You’ll pay extra for parts like brake shoes ($80-120), wheel bearings ($50-100 per wheel), gas bottle recertification ($25-35), and any seal replacements ($20-50 per seal).

If major issues are found, like water damage or worn suspension components, repair costs can run into thousands of dollars. This is why annual servicing is so valuable – catching problems early when they’re cheap to fix.

When To Book Your Service

Most manufacturers specify annual servicing based on the anniversary of purchase or first registration. However, the best time to service depends on your travel patterns and the van’s usage.

If you’re doing a Big Lap, service before you leave and again when you return, regardless of the calendar date. A van that covers 30,000km in 12 months needs more attention than one that sits in storage most of the year.

For full-time travellers, consider servicing every 6-8 months or 20,000km, whichever comes first. The constant use and varying road conditions put more stress on all systems.

Seasonal travellers should service before the travelling season starts. Getting your van serviced in January means any issues are sorted before you hit the road, rather than discovering problems when you’re 500km from the nearest town.

DIY Maintenance vs Professional Service

You can handle some maintenance tasks yourself, but certain jobs require professional skills and equipment. Here’s the realistic breakdown.

DIY Tasks

You can easily check tyre pressures, test lights and electrical accessories, inspect seals for obvious damage, and perform basic cleaning and lubrication. Water system sanitisation is also straightforward with the right chemicals and instructions.

Basic brake adjustments using the manual adjusters are within most people’s capabilities, and checking gas connections with soapy water is simple and effective.

Professional-Only Jobs

Wheel bearing inspection requires removing wheels and understanding what normal play feels like versus dangerous wear. Gas system pressure testing needs proper equipment and certification. Electrical safety testing, particularly for 240V systems, requires specialised test equipment and training.

Brake system work beyond basic adjustments should be left to professionals, as should any structural repairs or major appliance servicing. The cost of getting these wrong far exceeds the service fee.

The Middle Ground

Learn to do the basic checks yourself for peace of mind between services, but don’t skip the professional annual inspection. Your DIY skills complement professional servicing but don’t replace it.

Choosing The Right Service Provider

Not all service providers are equal. Here’s how to find one that’ll do the job properly.

Authorised Dealers vs Independent Workshops

Authorised dealers charge more but know your specific van’s quirks and have direct access to manufacturer updates and recall information. They’re essential for warranty work and often have better parts availability.

Independent workshops can offer better value and more personalised service, but make sure they’re experienced with your brand and have the right equipment for gas and electrical testing.

What To Look For

The best service providers have gas fitting licences, electrical testing equipment, and wheel bearing tools. They should provide detailed written reports and be willing to explain any issues they find.

Ask about their booking lead times – workshops that are booked months ahead are usually busy for good reasons. Check online reviews, but focus on recent ones as workshop quality can change quickly with staff turnover.

Mobile service providers are increasingly common and can be convenient, but ensure they have proper workshop facilities for major work like bearing repacks or brake replacements.
