The Cost of Preparing For a Big Lap: Cars, Caravans & Gear

The Big Lap has two budgets: the money you spend before you leave, and the money you spend on the road. This guide covers the first one, and for many people it’s the larger of the two. A caravan, a capable tow vehicle, and all the gear to set up for self-sufficient travel can cost anywhere from $15,000 to well over $200,000 depending on what you buy, whether you buy new or used, and how much you already own.

That range is enormous, and it’s meant to be. Some people do the Big Lap in a 15-year-old pop-top towed by a paid-off ute. Others do it in a brand-new off-road van behind a $100,000 LandCruiser. Both groups complete the lap and have an incredible time. The point isn’t to spend a specific amount. It’s to understand where the money goes so you can make deliberate choices rather than accidental ones.

Every Big Lapper’s upfront cost is different. The question isn’t how much to spend, it’s where to spend it wisely.

The Upfront Cost Reality

Here’s a realistic breakdown of what Big Lappers spend before departure, based on three common scenarios.

Budget setup (already own a tow vehicle): $15,000 to $40,000. Used caravan ($10,000 to $30,000), basic gear and setup ($3,000 to $5,000), vehicle servicing and preparation ($1,000 to $3,000), insurance ($500 to $1,500). This is the reality for many grey nomads with a paid-off 4WD and modest expectations for the van.

Mid-range setup (buying both vehicle and van used): $50,000 to $100,000. Used tow vehicle ($25,000 to $50,000), used caravan ($20,000 to $40,000), gear and setup ($5,000 to $8,000), vehicle prep and modifications ($2,000 to $5,000), insurance ($1,000 to $2,000). This covers a family buying a reliable Prado or Ranger and a well-maintained 5 to 10 year-old caravan.

Premium setup (buying new): $120,000 to $250,000+. New tow vehicle ($60,000 to $100,000+), new caravan ($50,000 to $120,000+), gear and setup ($5,000 to $15,000), modifications ($3,000 to $10,000), insurance ($1,500 to $3,000). This is the full buy-everything-new scenario. Comfortable, but a significant financial commitment.

Most Big Lappers fall somewhere in the mid-range. And most who’ve done it will tell you that the van and vehicle only need to be good enough, not perfect. Money saved on the setup goes directly into making the trip longer, more comfortable, or less financially stressful.

The Caravan

The caravan is typically the largest single purchase. The price range is vast because the market spans everything from basic pop-tops to luxury off-road vans with lithium batteries, rooftop solar, and king beds.

Budget: $10,000 to $30,000 (used). Older vans (8 to 15 years) in reasonable condition. Expect basic layouts, older appliances, AGM batteries, and limited off-grid capability. They’ll do the lap on sealed roads with regular caravan park stops, but they’ll need more maintenance and may lack modern comforts. Inspect thoroughly before buying; water damage in older vans can be expensive to repair.

Mid-range: $30,000 to $70,000 (used or entry-level new). The sweet spot for most Big Lappers. A 3 to 8 year-old well-maintained van with a functional layout, decent power system, and reliable build quality. Or an entry-level new van with a warranty and modern features. This range gets you a van that’s comfortable, capable, and won’t need constant attention on the road.

Premium: $70,000 to $150,000+ (new, high-spec). Full off-road capability, lithium batteries, 400W+ solar, independent suspension, composite construction, premium appliances. These vans are built for extended travel in harsh conditions and they deliver. Whether you need this level of spec depends on your route, your towing capacity, and your budget.

The Tow Vehicle

If you already own a vehicle that can safely tow your caravan within all weight limits, this cost is zero beyond servicing. If you need to buy, upgrade, or change vehicles, it’s the second-largest expense.

Budget: $15,000 to $30,000 (used, older model). An older Patrol, LandCruiser 100 Series, Pajero, or D-Max. Mechanically sound but with higher kilometres and older technology. These vehicles tow well and are proven on the Big Lap. The trade-off is potentially higher maintenance costs and lower fuel efficiency.

Mid-range: $30,000 to $60,000 (used, 3 to 8 years old). A LandCruiser 200 Series, Prado 150, Ranger, HiLux, or D-Max with reasonable kilometres and a service history. Modern safety features, better fuel efficiency, and more comfortable for long-distance towing. This is the range most Big Lap families land in.

Premium: $60,000 to $100,000+ (new or near-new). A new 300 Series LandCruiser, new Patrol, or top-spec ute. Warranty coverage, latest safety technology, best fuel efficiency. The highest upfront cost but the lowest risk of mechanical problems. Availability and wait times for new vehicles can be significant; order early.

The most important factor isn’t the price; it’s the match between the vehicle’s towing capacity and your caravan’s loaded weight. A $25,000 Pajero that’s within its limits is a better choice than a $70,000 ute that’s at its maximum.

The best tow vehicle is the one that matches your caravan’s weight with margin to spare. Not the most expensive one on the lot.

Gear & Setup

Everything that goes in, on, and around the van to make it liveable for months on the road. This category creeps up on people because each item seems small until you add them all together.

Essential gear: $2,000 to $5,000. The must-haves: electrical cables, water hoses, levelling gear, basic tools, first aid kit, fire extinguisher, outdoor chairs and table, camp mat, cooking basics (pots, pans, plates, utensils), bedding, and cleaning supplies. These are the things you literally cannot start the trip without.

Comfort and convenience: $1,000 to $5,000. The nice-to-haves that become essentials after the first week: a good mattress topper, quality outdoor furniture, a BBQ, a decent coffee setup, extra storage solutions, and kitchen gadgets that make cooking in a small space bearable.

Off-grid and power: $500 to $10,000+. The biggest variable. If your van comes with adequate solar, batteries, and an inverter, this cost is minimal. If you need to upgrade from AGM to lithium batteries, add solar panels, install a DC-DC charger, or add an inverter, the costs add up quickly. A basic lithium battery upgrade alone can cost $1,500 to $4,000. A full off-grid power system (batteries, solar, inverter, monitoring) can run $5,000 to $10,000+.

Connectivity: $200 to $2,000. A Telstra SIM and a decent data plan ($50 to $80/month) is the minimum. A signal booster ($500 to $1,200) extends coverage. Starlink ($800 hardware + $139 to $180/month) is the premium option for reliable internet anywhere.

Vehicle Preparation & Modifications

Separate from the purchase price, both the vehicle and caravan need preparation before a 20,000 to 40,000km trip.

Vehicle servicing: $500 to $2,000. A comprehensive pre-departure service including oil, filters, cooling system, transmission, brakes, suspension inspection, and tyres. The higher end covers replacing items that are serviceable now but won’t last the full trip (brake pads at 40%, tyres at 4mm tread, ageing coolant hoses).

Vehicle modifications: $0 to $10,000+. Suspension upgrades ($1,500 to $4,000), a bull bar ($1,000 to $3,000), driving lights ($200 to $1,000), a dual-battery system if not already fitted ($500 to $2,000), UHF radio ($200 to $500), and a reverse camera ($200 to $800). Not all of these are essential; prioritise based on your route and van.

Caravan preparation: $200 to $2,000. Gas compliance check, bearing inspection and repack, seal inspection and repair, brake check, safety equipment check, and any minor repairs identified during inspection. For used vans, add a professional pre-purchase inspection ($300 to $500) if you haven’t already done one.

Preparation costs $500 to $2,000. Skipping it costs significantly more when something fails 500km from the nearest town.

Putting It All Together

Here’s what the total upfront investment looks like across the three scenarios, summarised.

These numbers look intimidating, particularly at the upper end. But remember: the caravan and vehicle retain significant resale value. A $50,000 caravan used for 12 months might sell for $35,000 to $45,000. A $60,000 vehicle might sell for $45,000 to $55,000. The Big Lap doesn’t cost you the purchase price; it costs you the depreciation, plus the gear and running costs. For many setups, the actual “cost” of the vehicle and van is 15 to 30% of the purchase price.

Don’t let the upfront numbers stop you from starting. Start with what you have, buy used where possible, and spend money on the things that affect your daily experience (a good mattress, reliable power, functional kitchen) rather than the things that impress people on Facebook (chrome accessories, brand names, unnecessary upgrades).
