Choosing the right self-contained vehicle for your Big Lap is one of the most important decisions you’ll make. Get it wrong, and you’ll be uncomfortable, overpacked, or struggling with mechanical issues thousands of kilometres from home.
The good news? There’s a perfect option for every type of traveller. Campervans suit minimalist couples, motorhomes work for families who want hotel-level comfort, and converted buses offer the ultimate in DIY customisation. Each has distinct advantages and drawbacks that become critical when you’re living in them for months at a time.
This guide breaks down every option so you can make an informed choice based on your budget, travel style, and mechanical confidence.
Campervans: Compact and Nimble
Campervans are built on commercial van chassis, typically Toyota HiAce, Mercedes Sprinter, or Ford Transit. They’re the most car-like to drive and can access places larger vehicles simply can’t reach.
The Pros
- Fuel efficiency: Expect 8-12L/100km depending on size and driving conditions
- Access: Fits in regular car parks and can navigate narrow beach tracks
- Running costs: Cheaper tyres, parts, and servicing than larger vehicles
- Easy to drive: Most feel like driving a large car rather than a truck
- Stealth camping: Less conspicuous for overnight stops in towns
The Cons
- Space limitations: Standing height only in the centre for most models
- Storage: Every cubic centimetre matters when packing
- Weather dependence: Less comfortable during extended wet weather
- Privacy: Difficult to separate living areas or find alone time
- Water and waste capacity: Frequent tank fills and dumps required
High-top campervans offer full standing height but sacrifice fuel economy and wind resistance. Low-top models are more aerodynamic but you’ll be crouching inside.
Popular Australian brands include Winnebago (Mossman and Europa models), Jayco (Conquest range), and numerous custom converters. Expect to pay $80,000-$150,000 for a quality new campervan, with used examples from $40,000-$80,000.
Motorhomes: Maximum Comfort
Motorhomes are purpose-built on truck chassis with coach-style bodies. They prioritise living space and comfort over driving dynamics, essentially bringing your home on wheels.
The Pros
- Living space: Full standing height, separate bedroom, lounge, and bathroom areas
- Storage: Massive internal and external storage compartments
- Tank capacity: 100-200L fresh water, 80-150L grey water typical
- Comfort features: Air conditioning, full-size fridge, proper shower
- Weather protection: Comfortable during extended bad weather periods
The Cons
- Size restrictions: Can’t access many beaches, national parks, or narrow roads
- Fuel consumption: 15-25L/100km depending on size and conditions
- Driving complexity: Requires confidence with large vehicles, different licensing may apply
- Running costs: Expensive tyres (from $400+ each), costly repairs
- Parking challenges: Limited overnight options in towns and cities
Class A motorhomes (coach-style) range from $200,000-$500,000+ new. Class C motorhomes (cab-chassis with coach body) start around $150,000 new. Quality used motorhomes begin around $80,000 but depreciation is significant in the first five years.
Check GVM (Gross Vehicle Mass) ratings carefully. Many motorhomes are close to their weight limit even when empty, leaving little payload for personal belongings.
Converted Buses: Custom Builds
School buses, coaches, and other commercial vehicles converted for living. Popular with DIY enthusiasts who want a unique, personalised setup without the premium of manufactured RVs.
The Pros
- Customisation: Build exactly what you want, where you want it
- Value: Significantly cheaper than equivalent manufactured RVs
- Robust chassis: Built for heavy commercial use and long life
- Character: Unique appearance and conversation starter
- Learning experience: Develop mechanical and construction skills
The Cons
- Time investment: Conversion takes months or years of work
- Skill requirements: Electrical, plumbing, and construction knowledge needed
- Compliance issues: Registration and insurance can be complex
- Resale value: Difficult to sell, very personal builds
- Mechanical unknowns: Buying used commercial vehicles carries risks
Base vehicles range from $15,000-$50,000 depending on age and condition. Budget another $20,000-$80,000 for conversion materials, plus hundreds of hours of labour. Professional conversions start around $80,000 total.
Truck Conversions: Heavy-Duty Options
Military trucks, expedition vehicles, and heavy-duty 4WDs converted for extended travel. The choice for serious off-road adventurers who prioritise capability over comfort.
The Pros
- Off-road ability: Can access remote locations others can’t reach
- Durability: Built for harsh conditions and heavy loads
- Ground clearance: High clearance for rough tracks and creek crossings
- Towing capacity: Can tow boats, trailers, or cars behind
- Self-sufficiency: Large fuel and water tanks for extended remote stays
The Cons
- Fuel consumption: 20-35L/100km typical for larger military vehicles
- Comfort compromises: Road noise, harsh ride, basic amenities
- Maintenance complexity: Specialist knowledge and parts required
- Size limitations: Too large for many standard camping areas
- Registration hurdles: Complex compliance for ex-military vehicles
Many truck conversions require Heavy Rigid (HR) or higher licences to drive legally. Check weight ratings and licensing requirements before purchasing.
