The Off-Road Buyer’s Guide
Campers, caravans and motorhomes. How to choose one that suits the trip you actually intend to take.
Most people who regret their purchase did not buy a bad van. They bought a perfectly good van built for a different trip than the one they ended up taking. This guide works through the decisions in the order that matters: trip first, weights second, construction third, fit-out last. The four sections below are the complete text from the guide, nothing held back.
Start with the trip, not the van
Every specification decision downstream, payload, water capacity, battery bank, suspension travel, bed layout, is answered by the trip. Get the trip honest and the van almost specifies itself.
The honesty test
There is a gap between the trip people describe when they walk onto a lot and the trip they take. The described trip is usually the Canning Stock Route. The actual trip is usually six weeks up the coast with a fortnight of genuine remote work in the middle. Both are excellent trips. They need different vans.
A useful way to cut through it: think about the last three holidays you actually took, not the ones you talked about. Then ask what would have had to change for the van to be the limiting factor.
The nine questions
- How many nights a year? Under 30 nights changes the maths completely, depreciation and storage start to dominate over capability.
- How many consecutive nights off-grid? Two nights is a solar-and-battery question. Fourteen nights is a water-and-waste question, and water is heavier than everything else you carry.
- What is the worst surface you will genuinely tow on? Be specific. “Gravel access road” and “Gibb River Road” are not the same engineering problem.
- Who is travelling? Two adults, or two adults plus grandchildren twice a year? The second one has caught out a lot of people who bought a couples van.
- What is your tow vehicle, and will you change it? If not, the vehicle is a hard constraint and section 2 will do most of your shortlisting for you.
- How much setup are you willing to do at 4pm in the rain? The single most underrated question in the process.
- Caravan parks, national parks, or free camps? Park-heavy travel means powered sites and dump points, which relaxes almost every off-grid requirement.
- Do you need an internal bathroom? It costs length, weight, water, waste capacity and money. For some travellers it is non-negotiable; for others it is the thing they would drop first.
- What is the resale horizon? Three years and five years are different purchases.
We describe ourselves as lazy campers, and we mean it as a design standard rather than a confession. If setup takes forty minutes, you will stop doing one-night stays. You will push on to the next town instead of pulling into the good spot you passed. Over a long trip, slow setup quietly shrinks where you go. Time a full setup and pack-down on any van you are seriously considering, with a stopwatch, at the dealership, before you buy.
The weights that bite
The least glamorous section here and the one that prevents the most expensive mistakes. Weight is where enthusiasm meets the law, and the law does not negotiate.
The vocabulary
| Term | What it means | Where to find it |
|---|---|---|
| Tare | The van as it left the factory, empty. Check what the manufacturer included, gas bottles and water are treated inconsistently. | Compliance plate |
| ATM | Aggregate Trailer Mass. Maximum the loaded van may weigh when not coupled. Includes ball weight. | Compliance plate |
| GTM | Gross Trailer Mass. Maximum that may sit on the van’s axles when it is coupled. ATM minus ball weight. | Compliance plate |
| Payload | ATM minus tare. Everything you own, eat, drink and carry. | Calculate it yourself |
| Ball weight | Downward mass on the tow ball. Commonly 8 to 12% of ATM on off-road vans. | Weigh it, do not trust the brochure |
| GVM | Gross Vehicle Mass. Maximum loaded weight of your tow vehicle alone, including the ball weight pressing down on it. | Vehicle placard |
| GCM | Gross Combination Mass. Maximum for vehicle and van together. | Vehicle placard |
The GCM trap
Here is the one that catches experienced people. Your vehicle has a GVM and a maximum towing capacity. Add them together and you will usually get a number larger than the GCM. That is not a misprint, it means you cannot legally use both maximums at once.
A common dual-cab: GVM 3,050 kg. Braked towing capacity 3,500 kg. Added together, 6,550 kg. But the GCM is 6,000 kg.
So if you tow a van loaded to its full 3,500 kg ATM, your vehicle may only weigh 2,500 kg, roughly its kerb weight before you add passengers, fuel, a bullbar, drawers, a fridge, or the 350 kg of ball weight the van puts on your towbar. You are over before you pack a single shirt.
The shortfall is 550 kg. That is not a rounding error. That is the whole family.
The payload trap
Manufacturers advertise ATM because it is a big number. Payload is the number that governs your life. A van with a 3,500 kg ATM and a 2,900 kg tare gives you 600 kg. That sounds generous until you start filling it:
| Item | Realistic weight |
|---|---|
| Fresh water, 180 L | 180 kg |
| Two full gas bottles (9 kg) | 38 kg |
| Food, clothing, bedding, kitchen for two | 90 to 130 kg |
| Tools, recovery gear, spares, second spare wheel | 60 to 100 kg |
| Generator or extra battery | 20 to 40 kg |
| Awning walls, mats, chairs, table, camp kitchen | 40 to 70 kg |
| E-bikes or similar, if carried | 50 to 80 kg |
| Typical total | 478 to 638 kg |
Water is the surprise for most people. It is the heaviest single thing you carry, and the more remote you go the more of it you need. A van marketed for extended off-grid travel with only 400 kg of payload is quietly telling you it does not expect you to fill its tanks and load it at the same time.
What to actually do about it
- Get the rig weighed loaded, at a public weighbridge, before your first big trip. Four corners if you can, side-to-side imbalance is common and rarely suspected.
- Treat any payload figure under 500 kg on a full off-road van as a serious question, not a detail.
- Ask whether the tare on the plate is for that exact van or a representative model. An option-heavy build can be 150 kg heavier than the brochure.
- Remember ball weight is carried by the vehicle, not the van. It consumes your GVM, not your ATM.
Build categories, honestly described
The words “off-road” and “outback” appear on almost everything sold in this country, including vans that should not leave bitumen. There is no legal definition and no certifying body. Judge the build, not the badge.
| Category | Genuinely suited to | Trade-offs |
|---|---|---|
| Touring / on-road | Bitumen and well-maintained gravel. Caravan parks and popular national parks. | Lightest and cheapest to buy and tow. Will be shaken apart by sustained corrugations. |
| Semi off-road | Formed dirt roads, station tracks, most gravel access to free camps. | The widest quality spread of any category. Some are genuinely capable; some are touring vans with chunky tyres. |
| Full off-road caravan | Sustained corrugations, remote travel, extended off-grid living with a full internal bathroom. | Heaviest and most expensive. Demands a serious tow vehicle. Length limits where you can turn around. |
| Hybrid / expedition camper | Difficult tracks, tight campsites, couples who prioritise access over interior space. | Compact and capable, with a far better departure angle. Less internal living space. |
| Off-road camper trailer | The most difficult terrain, shortest setup-to-sleep on soft ground, lowest cost of entry. | Setup time varies enormously by design. Limited wet-weather living space. |
| 4WD motorhome | Solo travellers and couples who want one vehicle, no reversing, and fast overnight stops. | You lose your day vehicle once you set up camp. More complex and costly to service. |
The one comparison worth making yourself
Caravan versus hybrid is the decision most couples agonise over, and it comes down to a single trade: interior space against access and setup speed. A hybrid gets you into campsites a full-size van cannot reach and gets you sleeping faster. A caravan gives you somewhere pleasant to sit when it rains for three days.
A practical way to resolve it: think about your worst-weather day, not your best. If four wet days indoors sounds miserable in a hybrid, buy the caravan. If you would rather be somewhere a caravan cannot go, buy the hybrid and accept you will sit outside under an awning more often.
Motorhomes are chronically under-considered in Australia because the caravan marketing budget is larger. For a solo traveller, or a couple doing lots of one-night stops between destinations, a 4WD motorhome can be the obvious answer: no reversing, no coupling, no setup beyond a handbrake. The real question is whether you can live without a separate day vehicle.
Dealer or private
The same van is usually a few thousand dollars cheaper privately. That gap is not dealer greed, it is the cost of the work done to the van before it is offered, and the protections that work makes possible. Whether it is worth paying depends entirely on what you get for it, so ask.
Five things to ask any dealer selling a used van
None of these are universal. Some dealers do all five, some do none, and the price will look similar either way. The answers are the whole difference between the two prices.
1. Has it been serviced, and is that included?
A properly presented used van should come to you freshly serviced, so you are not due again for another year or ten thousand kilometres. Buy privately and you are almost always paying for a service in your first month, on top of the purchase.
2. Is there an inspection report, and can I see it?
A thorough pre-sale inspection runs to something like fifty points: brakes, bearings, suspension, chassis, seals, batteries, charging, water, gas, air-conditioning, appliances. What matters is not that it happened but that you get to read it. Something essential gets fixed before the van is offered; something non-essential gets disclosed so you can decide whether to upgrade it.
3. Roadworthy, and is that the same as ready to camp in?
A roadworthy asks whether the van is safe to tow on a public road. It does not ask whether the fridge works, whether the seals are sound, whether the hot water runs, whether the batteries hold charge, or whether you could live in it for a fortnight. Vans do pass a roadworthy while being perfectly towable and not remotely campable. If a seller offers a roadworthy as evidence of condition, they are answering a different question to the one you asked.
4. Can I buy extended warranty cover with it?
Extended warranty cover is issued as part of the contract of sale, and it requires the van to be roadworthy, structurally sound and with appliances operational when the cover is bought. That is only demonstrable off the back of a service, an inspection and a roadworthy, which is why it is available on a dealer sale and not a private one.
You cannot buy privately, have the van serviced next month and then take out extended cover. The cover attaches to the sale. On a used van with appliances out of their original warranty, that usually matters.
5. What does the handover involve?
A private handover is whatever the seller knows and has time for. The difference shows up later and dealers see it plainly: in where owners are willing to travel, how the van has been maintained and stored, and what it is worth in five years. Someone shown how to level it properly, what to check after corrugations and how the charging system works looks after the van differently.
A note on consignment
Some used vans on a dealer’s floor are consignment units, still owned by the previous owner and sold through the dealer’s process. To you as a buyer this changes nothing, the same service, inspection, roadworthy and handover apply. It matters to the seller, who gets more than a trade-in price.
If you are buying privately, do these five things
- Run a PPSR search before you hand over money. A couple of dollars tells you whether there is finance owing, whether it has been written off, and whether it is reported stolen. If money is owing, the financier can repossess it from you.
- Pay for an independent inspection, not the seller’s mechanic. This is you buying the report a dealer would have handed you.
- Check the compliance plate against the paperwork and the VIN against the registration.
- Ask for all the service records, and budget for a service immediately.
- Weigh it loaded at a public weighbridge. Everything in section 2 applies to a used van.
What actually transfers with the van
- The builder’s warranty often transfers, but rarely automatically, usually registration with the manufacturer inside a short window, thirty days being common.
- Component warranties frequently do not transfer at all. Fridges, heaters, air-conditioners, batteries and suspension are commonly warranted to the original owner only.
- An existing extended warranty can usually transfer, for a fee, within a deadline, and with the complete service history.
Price this in. A private van with no appliance cover and no service, against a dealer van with both and an inspection report you can read, is a smaller gap than the sticker suggests, and sometimes no gap at all.
When private genuinely is the better buy
If the van is well out of its original warranty, if you are mechanically confident, and if you will do the PPSR check and pay for a proper inspection, private can be excellent value. Where it goes wrong is buying a van still inside warranty and assuming the cover comes with it, or treating a roadworthy as a condition report.

Disclaimer. This guide is general information prepared to help you ask better questions. It is not advice about any specific vehicle, and weight figures, regulations and specifications change. Always verify weights against the compliance plate of the actual van and the placard of your actual vehicle, and have any loaded rig weighed at a public weighbridge before travelling.
