4 berth campervan hire blue mountains, with room for wet boots

A typical 4 berth motorhome Blue Mountains setup is not a hotel room on wheels, and that is the point. You usually get a double bed over the cab plus a second double made from the rear or mid dinette, a compact kitchen, fridge, toilet/shower cubicle, fresh and grey water tanks, and enough cupboards for sensible packing. If you bring four hard suitcases, the van will punish you with physics.

For two adults and two kids, a 4 berth is the sweet spot: everyone has a bed, wet jackets can hang inside, and you are not driving something that feels like a delivery truck on Scenic Drive. For four adults, it works best when everyone is friendly, tidy, and not precious about making the bed before coffee.

• Do: pack soft bags, not rigid cases; they squash into lockers and under seats.
• Do: choose a layout with internal toilet/shower if you want unpowered or national park nights.
• Don't: assume every 4 berth camper Blue Mountains listing has the same bed sizes — check the floorplan before you book online.

Most 4 berth campervans sit around 6.7 to 7.7 metres long, about 2.2 metres wide and 3.0 to 3.4 metres high. You can drive them on a standard car licence if the vehicle is under 4.5 tonnes GVM, which most rental motorhomes are. The Great Western Highway is sealed all the way to Katoomba, Blackheath and Lithgow, but it is still a mountain road: long climbs, fog, impatient commuters and the occasional B-double sitting on your bumper like a moral judgement.

You will not meet Pilbara road trains in Katoomba, but head west past Lithgow and the country opens fast. Katoomba to Cobar is roughly 560 km, and by then fuel planning and overtaking etiquette matter. Let big rigs pass where safe, keep left unless overtaking, and do not brake hard for every lookout sign unless you want a ute in your kitchen sink.

• Height: avoid underground car parks and check tree branches in older streets around Leura and Blackheath.
• Parking: arrive early at Echo Point and popular walk starts; weekend spaces fill by late morning.
• Don't: take tight side streets just because a phone map says it is 90 seconds quicker.

A 4 berth campervan hire Blue Mountains trip is easiest with a mix of powered holiday park nights and simpler unpowered stops. Powered sites help you run 240V appliances, recharge devices, use heating in winter and reset the van after muddy walks. Unpowered sites are fine for a night or two if your auxiliary battery, water and gas are behaving.

Free camping is not the same as sleeping anywhere with a view. In NSW, you need to use places where overnight camping is allowed, and many Blue Mountains streets, lookouts and car parks are patrolled. National park campgrounds usually require online bookings, even when facilities are basic, and the Glenbrook area of Blue Mountains National Park has a vehicle entry fee of about $8 per vehicle per day.

• Powered holiday park: best first night, best after rain, best with kids who need showers.
• NP campground: quieter, but book ahead and expect limited bins, showers or phone reception.
• Free camp: useful west of the mountains, but check signs and local rules before putting the kettle on.
• Don't: overnight at a lookout unless it is specifically signed as a campground.

Most 4 berth motorhomes run diesel with a 70 to 90 litre tank. Expect roughly 10 to 14 L/100 km depending on weight, wind, hills and how enthusiastically you climb Victoria Pass. That gives a practical range of about 550 to 750 km, but do not run it to the light; Blue Mountains weather can turn a simple drive into a slow one, and servos are much more cheerful before you need them.

Along the M4 and Great Western Highway, fuel is easy at Penrith, Springwood, Katoomba, Blackheath and Lithgow. If you push towards Mudgee, Bathurst or the Central West, top up at larger towns. LPG for cooking, hot water and sometimes heating is usually a 4.5 kg or 9 kg bottle; in cold weather, heating can chew through gas faster than expected. A servo, hardware store or larger town is your friend. The bottle-o can wait until after you have parked.

• Fresh water: commonly 80 to 110 litres; four people may use that in 2 to 3 days if showering onboard.
• Grey water: empty only at approved dump points or park facilities, never down a street drain.
• Toilet cassette: plan a dump-point stop every 2 to 3 days with four aboard.
• Do: check the pickup map for dump points near Katoomba, Lithgow or Bathurst before committing to free nights.

Katoomba sits around 1,017 metres above sea level, so it can be 8 to 12°C cooler than Sydney. Winter nights often drop to 0 to 5°C, summer days can be a pleasant 22°C or a smoky 35°C heatwave, and fog can erase a famous view with comic timing. A 4 berth camper gives you shelter for the wet and space for drying socks, which sounds dull until day two of drizzle.

The Blue Mountains also teach useful van habits before a longer lap: water discipline, battery discipline, reversing into tight sites, and knowing when not to follow a gravel road. Many hire agreements restrict unsealed roads except short campground access roads. Places like the Glow Worm Tunnel road, Newnes tracks, Kanangra Walls Road or rough Wollemi fire trails can be corrugated, steep, closed after rain or simply outside your rental conditions.

• Do: check road closures on NSW National Parks and Live Traffic NSW before leaving sealed roads.
• Do: carry at least 5 litres of drinking water per person on longer walks, separate from the van tank.
• Don't: treat a 2WD 4 berth motorhome like a 4WD just because the first kilometre of dirt looks friendly.
