This is the way to see the world from ground level: A purpose-built, go-anywhere 6x6 mobile home with all the toughness and dependability of a Toyota along with global access to the brand’s parts and repair program.

Based on the Land Cruiser 79 Series platform, the Australian-designed and built Earthcruiser Extreme 330 XTR 6x6 is available for order and billed as having the specifications and equipment list to conquer the world’s toughest terrains safely, reliably and comfortably.

The Earthcruiser, developed over 12 months and drawing from its sibling models, is made to allow owners to spend extended time on the road, hence its ability to be used in global markets and evident by its 275-litre fuel capacity.

The company behind the Extreme 330 XTR 6x6 program said it began as a special custom build for a valued customer, but word got out about the build and Earthcruiser’s order book for the vehicle started to fill quickly.

Under the body is a drive system developed by respected 6x6 conversion specialists, 6x6 Australia, and features a clever bogie drive system with a unique coil/airbag sprung bogie drive rear axle set-up, with full load sharing capability between each rear axle.

It has a drive-through diff and power divider with the third axle remaining undriven while the vehicle is on bitumen. When the vehicle senses it is losing traction, the power divider locks up 100 per cent drive to all wheels.

The three axles also have the same track width for easier wheel placement when tackling obstacles.

For extra strength, the fully-fabricated rear axle/diff housings have a 3600kg load rating each. A variable ratio rear-steer feature also provides variable steering assistance from the rear bogie based on turn radius and speed.

The drivetrain also has three differential locks — which can be engaged at the same time via in-cabin switches — and a low-range transfer case which is matched to a six-speed genuine Toyota automatic transmission. Available as an option is the standard manual gearbox with a strengthened clutch.

The portal axles provide a 5-inch (125mm) lift along with a huge 390mm of under-axle clearance at the diff. The portals have been FEA (Finite Element Analysis) tested and certified to over 1500kg each (3000kg per axle) and include a CTIS (Central Tyre Inflation System) that supplies air to the tyres through the hub centre.

Inflation and deflation can be actuated simultaneously to all wheels while the vehicle is in motion using a Garmin in-cabin and removable digital touchscreen. The system can also be programmed to automatically adjust air pressures based on road speed.

The vehicle also gets a full airbag suspension system with automatic load and horizon levelling and three height modes – kneel, ride and lift – with up to 100mm difference between the lowest and highest modes.

Up to 250mm of variation can be achieved in manual control mode but this feature is not for driving purposes.

Chassis clearance at ride height is 610mm and complementing the airbags are military-spec heavy-duty sway bars with an in-cabin disconnect function that allows greater articulation off road.

For maintenance, the Earthcruiser has four hydraulic rams used for underbody repairs including changing wheels without using the manual jack.

Standard wheels and tyres are 17-inch forged-alloy rims with dual inflation valves and 35-inch by 12.5-inch Federal Xplora mud terrain tyres with 137Q load rating (2300kg per tyre).

Because of the scale of the vehicle, the equipment fitted and its 4130mm wheelbase, the truck has an upgraded 7000kg GVM which has been fully engineered and is registerable federally via SSM (Second Stage of Manufacture).

The front axle capacity is also 500kg higher than stock at 1980kg. The company said that these changes provide owners with 3000kg payload that is in addition to the outfitted camper body.

To handle the added mass, the Extreme 330 XTR 6x6 is equipped with a hydraulic brake booster that reduces braking effort while increasing responsiveness; upgraded calipers and oversized heavy-duty vented brake rotors have also been specified to increase stopping power. It also has the surety of an electric parking brake that actuates on all four rear calipers.

Earthcruiser said that it does not perform engine upgrades or tuning but can introduce prospective buyers to its trusted partners that can help with any tuning or remapping.

Protective bar work includes a hammer-tone textured deluxe winch compatible steel bullbar and protective steel scrub rails and side steps, which is colour coded to the bullbar; and there are heavy-duty front and rear recovery points if needed. Further assisting in vehicle recovery are two 13,000lb 12-volt electric winches both front and rear.

Two spare wheel carriers with electric ‘wheel lifters’ are also fitted to the truck for effortless tyre changing, while a dual-purpose Maxtrax / fire-wood carrier allows owners to carry up to for Maxtrax and a load of firewood simultaneously.

Inside the cabin, Earthcruiser has upgraded the Land Cruiser’s factory features including re-modelled and retrimmed driver and passenger seats for greater comfort and aesthetics, and adding full sound and vibration dampening and heat insulation.

The cabin has crawl-through access to the camper. The rear section has two additional seat belted positions to give occupant capacity of four people. There is sleeping for three people.

The camper body has structurally insulated foam walls and floor and a one-piece infusion moulded structural foam roof that’s closed with double seals. The entry door is also insulated and has a deadlock while all latches and locks are flush mounted or recessed.

There is also a triple-layer block-out roof curtain, incorporating PVC windows, insect and full privacy screens with the materials rated from -30 to +70C.

Inside there are also leather dinette seats, precision CNC-routed Corian benchtops, a stainless-steel sink with a separate purified drinking fountain and freshwater wash taps.

It has internal and external showers with immediate and continuous hot water and central air heating – both diesel-powered. On board water capacity is 275-litres and there’s also a 27-litre grey water tank.

Earthcruiser has also fitted a split-system air conditioner, microwave oven, two-burner induction cooktop, two fridges, washing machine and dryer, and an Arctic System that heats the water tanks.

There is also a slide-out Thetford chemical toilet ensuite and an integrated high-pressure water cleaner.

The Extreme 330 XTR 6x6 features a full lithium-ion battery system for start and house batteries, 810w mono-crystalline solar panels, a 3000w Victron inverter, a 50amp multi-country Victron battery charger with 200amp high output and a fully sealed and water-cooled brushless alternator ensuring reliable power no matter what the location.

Along with traditional UHF communications, the camper has a Starlink satellite system providing easy internet access while allowing owners to view and track their vehicle from their phone anywhere in the world.

Storage areas, lockers and toolboxes are plentiful throughout the vehicle offering secure stowage that’s also easy to access.

Earthcruiser said it can offer prospective owners virtually limitless options to specify and accessorise their Extreme 330 XTR6x6 to meet their exact needs. More details at
