A used 4WD and a second-hand caravan are the classic way to explore Australia, from the Gibb River Road to a beach campsite on the Gold Coast. But many used 4WDs for sale and caravans for sale on classifieds sites are private sales, where you carry more of the risk. This checklist walks you through every step, in order, so you buy with confidence.
In this guide:
- Plan before you buy
- Check the paperwork
- Inspect the vehicle and van
- Buy safely
Part 1: Plan Before You Buy
Set a total budget
The asking price is only the start. Allow for:
- Stamp duty, registration and CTP insurance (these vary by state)
- Comprehensive insurance for both the 4WD and caravan
- A pre-purchase inspection
- A brake controller, UHF radio, recovery gear and new tyres
- A 5-10% maintenance buffer
Choose the right 4WD
Popular used 4x4 options include the Toyota LandCruiser, Toyota Hilux, Ford Ranger, Isuzu D-MAX, Nissan Patrol and Mitsubishi Triton. Research the known issues for the exact model and year before you inspect.
Match your tow vehicle to the caravan
A caravan is only as safe as the vehicle pulling it. Compare the compliance plates on both:
- Towing capacity: the maximum braked weight your 4WD can tow
- GVM: the maximum your vehicle can weigh fully loaded
- GCM: the maximum weight of vehicle and van together
- ATM: the maximum your loaded caravan can weigh
- Tare and ball weight: the van’s empty weight and the downward load on the towball
Many dual-cab utes tow well on paper but run out of payload once you add passengers, a bull bar and a full water tank. Do the maths first.
Part 2: Check the Paperwork
Run a PPSR check
A PPSR check is essential for any second-hand vehicle or caravan. It shows whether money is owing, whether the vehicle has been reported stolen, and whether it has been written off. If finance is owing, you could end up paying someone else’s debt. Check the VIN or chassis number yourself rather than trusting the seller’s paperwork.
Verify the history
Ask to see:
- Registration papers and a current rego check
- A full logbook or itemised service history
- Receipts for major work such as the clutch, turbo, suspension or timing belt
- For caravans, the compliance plate, gas compliance certificate and build documentation
Gaps in servicing are a red flag on a 4WD that has done heavy work, and the odometer should match the records.
Part 3: Inspect the Vehicle and the Van
Used 4WD inspection
Book a professional pre-purchase inspection through a mechanic or a motoring club such as RACQ, NRMA, RACV, RAC WA or RAA. Check:
- Underbody: rust, dents and bent parts around the sills, chassis rails and diffs
- Engine: cold start, smoke, oil leaks, and DPF or turbo problems on diesels
- Driveline: smooth gear changes, no clunks, and working high and low range
- Suspension and tyres: sagging springs, leaking shocks and uneven tyre wear
- Water damage: damp carpets, silt in the cabin or a musty smell
- Modifications: lift kits, bull bars, winches and snorkels must be legal and compliant in your state
Used caravan inspection
Book an independent caravan inspection and look closely at:
- Water leaks and damp: soft patches, stained ceilings or swollen panels. Water ingress is the costliest caravan repair.
- Chassis and drawbar: rust, cracks or poor welds, especially on off-road caravans
- Brakes, bearings and suspension: ask when the wheel bearings were last serviced
- Tyres: age matters more than tread, and tyres older than about 5-7 years should be replaced
- Gas and electrical: a compliant gas system, working 12V and 240V power, batteries and solar
- Appliances and seals: fridge, hot water, air conditioning, toilet, roof hatches and window seals
Take a proper test drive
Drive the 4WD at a mix of speeds and listen for vibrations, whining or clunks. If you can, test it with the caravan attached, because sway, poor braking or a sagging rear end often only show up under load.
Part 4: Buy Safely
Know your state’s rules
Roadworthy and transfer requirements differ across Australia. Queensland uses a safety certificate, Victoria a roadworthy certificate, and NSW has its own inspection and transfer process. Stamp duty and registration fees also vary. Buying interstate, such as a used 4WD in Brisbane while living in Sydney, means allowing for re-registration, inspections and transport. Confirm the details with your state transport authority before paying a deposit.
Understand private-sale protections
Private sales generally offer far fewer protections than buying from a licensed dealer, and usually no cooling-off period. Always get a signed receipt that records the price, VIN or chassis number, odometer reading and both parties’ details.
Pay safely
- Inspect in person, or send a trusted independent inspector
- Never pay a deposit for something you haven’t seen
- Be wary of sellers who rush you, push you off the platform or ask for gift cards
- Use a secure bank transfer and keep every record
- Meet in a safe, public place for the first viewing
Sort finance and insurance early
Compare car and caravan loan options before you commit, as some lenders limit the age of the vehicle or van. Get an insurance quote first, since 4WDs and caravans can cost more to cover.

FAQs
What is a PPSR check?
It is an online search of the Personal Property Securities Register that shows whether a vehicle or caravan has money owing, is stolen or has been written off.
How much does a pre-purchase inspection cost?
Prices vary by provider and location, so get quotes from a mechanic or motoring club before booking.
Can my 4WD tow any caravan?
No. The caravan’s ATM and your vehicle’s towing capacity, GVM and GCM must all stay within their limits.
