And you thought the regular LandCruiser 79 was tough.

    EarthCruiser Australia has revealed a six-wheel drive 79 Series motorhome designed to “conquer the world’s toughest terrains safely, reliably, and comfortably, allowing owners to spend extended time on the road”.

    Having started life as a special custom build for a “valued customer”, the Extreme 330 XTR6x6 has become a regular part of the EarthCruiser range.

    Under the skin, the Extreme features a 6×6 system that offers full-time four-wheel drive on the blacktop, before locking the third axle for six-wheel drive when slip is detected.

    Power comes from the standard 4.5-litre turbo-diesel V8 engine, mated with a Toyota six-speed automatic or a five-speed manual with a reinforced clutch. Total fuel capacity is 275 litres.

    There’s rear-wheel steering to make the car more manoeuvrable, along with a full suite of off-road goodies to take you deep into the wilderness.

    Portal axles allow for 390mm of ground clearance, and there are three differential locks. Drivers can use the Garmin touchscreen to remotely inflate or deflate the tyres – or the car can automatically do it based on how fast you’re going.

    A full airbag suspension system allows owners to choose from three heights: kneel, ride, and lift. There’s 100mm of difference between the three; owners are able to manually vary the ride height by up to 250mm at a standstill.

    Military-spec sway bars are on hand to keep the EarthCruiser’s considerable mass in check, but they can be disconnected from the cabin if required.

    If the 35×12.5in tyres need replacing the car is fitted with four hydraulic rams, negating the need to jack.

    With a 7000kg GVM, owners have a 3000kg payload. Bigger brakes and a bigger brake booster feature to keep the mass in check, along with an electric park brake.

    As for the motorhome on the back? The floor and walls are better insulated than the average Melbourne apartment, and the blockout roof and side curtains are rated from between -30 degrees and 70 degrees – making them appropriate for the average Melbourne winter, or Coober Pedy summer.

    Split system air-conditioning, a two-burner induction cooktop, and a full laundry feature, along with both internal and external showers.

    Water capacity is 275L, and there’s a 27L grey water tank.
