If you’ve got a spare $337,000 burning a hole in your pocket, you could probably buy a small unit in a dodgy suburb, or you could buy this Tommy Campers S6X. And honestly? This has better views.
Make no mistake about it, the things we ask our 4X4s to do these days are far beyond the imagination of the engineers who originally designed them. We want them to carry our house on their back, tow a boat, cruise at 110km/h in air-conditioned comfort, and then crawl up a goat track that would make a mountain goat nervous.
Usually, trying to make one vehicle do all that results in a compromised mess that drives like a boat and wheels like a brick. But then there’s ‘Big Tom’ by Tommy Campers. It’s what happens when you throw the chequebook at the problem and refuse to compromise on anything. But is it actually worth the eye-watering price tag? Let’s find out.

We all know the 79 Series LandCruiser is the 1955 Chev of the 4WD world. Solid. Old school. Will last forever and infinitely modifiable. But in stock form? It’s frankly a bit agricultural. To build a rig capable of carrying a slide-on camper through the Simpson Desert without snapping in half, the team at Tommy Campers knew a stock chassis wasn’t going to cut the mustard.
The backbone of this build is a JMACX Super Chassis. This isn’t just a patch job; it’s a full replacement rear end that converts the leaf springs to coils and stretches the wheelbase by 300mm. Why does that matter? Put simply, when you chuck a heavy camper on the back, you want that weight sitting in front of the rear axle, not hanging off the back like a heavy rucksack. The stretch balances the car, and the coil conversion—paired with Kings remote reservoir shocks means it actually handles corrugations instead of skipping over them like a stone on a pond.
They’ve also bumped the GVM up to a massive 4495kg. That gives you a legal payload that actually allows you to bring more than just a toothbrush and a change of undies.

Let’s talk grunt. The factory V8 diesel is lazy. It’s reliable, sure, but it wouldn’t pull a greased stick out of a dog’s backside in stock trim. To haul 4.5 tonnes of touring rig, Big Tom has been treated to a GTurbo G333 ti turbo and a custom tune. We’re talking 940Nm of torque. That is a serious number.
It breathes through a Jmax airbox and a fat 3.5-inch snorkel, exhaling via a Torqit 3.5-inch exhaust. It’s not about winning traffic light drag races; it’s about reliable torque when you’re slogging through soft sand or climbing a rocky range in low range. To keep it fed, there’s a Brown & Davis long-range tank setup carrying 300L of diesel (185L rear + 115L mid). That’s enough range to get you properly lost and back again.
This is what we’re here for. The S6X is Tommy Campers’ flagship slide-on. It sits on a custom heavy-duty tray with four toolboxes, but the genius is in the lift-off legs. Want to set up base camp and go wheeling? Drop the legs, drive out, and you’ve got an unladen 79 Series to play with.
Constructed from 3M aluminium, the shell itself weighs in at a lightweight 328kg (dry). Inside, it’s not exactly “roughing it”. You’ve got a 5-inch foam queen mattress that’ll keep you in bed longer than planned, a diesel heater for those frosty High Country mornings, and dual fans for when you’re sweating it out in the Top End.

The kitchen is a proper outdoor affair—which is how it should be in Australia. No one wants to fry bacon inside a small camper unless you want your pillows smelling like breakfast for a week.
Powering a rig like this isn’t a job for a cheap battery of eBay. The S6X is running a system that would power a small workshop. At the heart is the Redarc TVMS Rogue system.
This thing is clever. It controls everything from your lights to your water pumps, all accessible via the RedVision display or your phone. It’s paired with 300Ah of Redarc lithium batteries and a Manager 75. Why the 75? Because when you’re running induction cooking and a coffee machine, you need to put amps back in fast. There’s 400W of solar on the roof to keep it topped up when you’re off-grid.

Here’s the rub. $337,100. It’s an eye-watering amount of money. You could buy a 200 Series, a decent caravan, and still have enough left over for a lap of the map.
But that misses the point. The “tow-tug and van” combo limits where you can go. You’re not taking a 22ft caravan down the Telegraph Track unless you like talking to your insurance company. Big Tom is built to go anywhere a single vehicle can go, but with a level of comfort that a swag or rooftop tent just can’t match.
Is it over-capitalised? Maybe. But look at the components. The suspension and chassis stretch alone is $80k. The camper is $65k. The labour hours in the electrical install, the sound deadening, the custom bar work… it adds up. It’s a lot of money, but it’s not “expensive” for what it is—it’s just a lot of gear.
