He laughed when he picked up. That kind of dry, weary laugh that belongs to people who are doing too much and know it … but wouldn’t have it any other way. Three customer vehicles finished on Monday, he told me. One show car due this weekend. Then, maybe, a little breathing room for the Quartermaster project. The one bound for Dubai.

I imagined the scene: aluminium panels stacked against the wall, sparks still warm on the floor, and a black Grenadier sitting centre stage like a beast in mid-transformation. Around it, tools, jigs, cables, and a sense of quiet defiance. Black Sheep Innovations isn’t known for half measures. They build things that work, things that last. But this time, the bar was set even higher.

“We’re not just building another expedition truck,” he said. “We’re building something that proves what’s possible—even under pressure.”

Lessons from Sheepmaster One

The first Sheepmaster, built a couple of years ago, had been a revelation, but also a warning. It did everything it was meant to do: rugged, comfortable, self-contained. But it was heavy. Too heavy for Thomas’s taste. The new Quartermaster, Sheepmaster Two, would be different: stripped of excess, engineered to the gram, and focused on function.

“Every kilo matters,” he said. “When you’re overlanding, weight is the enemy. You learn that the hard way.”

This time, aluminium takes the lead. Not just in panels, but in the logic of how those panels come together. The structure is lighter, but stronger—overlapping, interlocking, folding into itself like a puzzle. Four walls and no full floor, just a rigid box that owes its strength to geometry as much as material.

Then there’s the clever part, how he uses the necessary kit as part of the design itself. The Maxtrax recovery boards aren’t simply bolted on; they’re recessed into the bodywork, each set sitting in a shallow cradle that doubles as a structural brace. The jerrycans, too, are half-sunk into the aluminium walls, their forms stiffening the box while providing vital fuel storage.

“People think of design in terms of aesthetics,” Thomas told me, “but for us, it’s always structure first. If you can make something functional and beautiful, great. But every curve, every recess, has to earn its place.”

He’s right. Look at the build long enough and you start to see it: a philosophy of economy, where nothing exists for show. Even the cut-outs and folds add stiffness. The result isn’t flashy. It’s purposeful. And that’s where the beauty lies.

Lightweight Doesn’t Mean Fragile

When he says “lightweight,” he doesn’t mean fragile. The rig is still built to take punishment. But rather than relying on thick plate and brute strength, he’s rethinking the way the structure carries its load.

The roof supports an Intrepid Geo 3.0 hard-shell tent, but even that has been re-engineered. The tent floor has been removed to create a direct access from the shell below. There’s no need to step outside in wind or rain. Gas struts will lift the bed, creating standing height and giving the space a sense of volume that’s rare in compact expedition setups.

Inside, the bed frame is still a work of mental engineering. It has to fold, tilt, and shift to make space for two people. “It’s not just furniture,” Thomas said, “it’s choreography.”

Every Millimetre Counts

Under the flatbed lies a masterpiece of packaging. When he first looked at the Grenadier’s chassis, he saw wasted space between frame and floor. To most builders, that void is too shallow to be useful. To Thomas, it was an invitation.

He spent two weeks measuring, adjusting, mocking up components until everything fit with millimetre precision. Into that space went an 18-litre air tank, air horns, a diesel heater, dual freshwater tanks (32 litres each), a pull-out kitchen box from MOKUBO, and additional storage modules—all neatly mounted on slides that extend a full metre and a half from the rear.

“We’ve got maybe two or three millimetres clearance left,” he said, almost proud. “But everything fits. It’s tight, but it works. And when it works, that’s a good feeling.”

A fold-out stair system tucks beneath, ready to deploy when needed. Every corner serves a purpose. The goal is not to show off, it’s to make sure that no space goes unused and no weight is wasted. Even the smallest detail is guided by an understanding of what happens when you’re thousands of kilometres from home and the terrain stops forgiving mistakes.

Simplify, but Add Function

Step inside the cabin and the same thinking continues. The rear bench is gone. A clean sixty-five kilos shaved straight away. In its place sits a partition and a practical workspace: a fridge on one side, a Milwaukee tool array on the other.

“We’ll be out there for weeks,” he said. “We need to be able to repair whatever breaks, wherever we are. There’s no calling a service truck.”

Milwaukee joined the project as a partner, providing a full suite of cordless gear. It’s a small victory in a build otherwise powered by sweat equity and long hours. “Sometimes,” he added, “when people believe in what you’re doing, they make the impossible a bit more manageable.”

Up front, new aluminium mounts are being machined for laptops, cameras, and comms devices—designed to match the cockpit’s lines rather than clutter them. The Delta Bags seat covers are already fitted, and five-point harnesses are coming next. Not for show, but for posture. “When you drive long distances, you start to collapse into the seat. This helps keep you upright. And, yes, it looks a bit like rally spec,” he admitted with a grin.

Power and Independence

Modern vehicles are ruled by electronics, and the Grenadier is no exception. But Thomas treats electrical systems the same way he treats everything else: understand it, simplify it, make it work.

“We’re not fans of the factory wiring,” he said bluntly. “It’s overcomplicated. Too many shared circuits. But you can’t just rebuild it—it’s too deep.”

Instead, they’ve re-routed what they could, lifted the looms higher to protect them from the terrain, and added layers of redundancy. The onboard power comes from an EcoFlow Delta 2 Max, fed by roof-mounted solar and an alternator booster. If the main batteries go down, the EcoFlow can backfeed and jump-start the system.

That’s independence … not in the romantic sense, but the practical one that keeps engines turning when things go wrong.

He’s also testing a Global Guard OBD module. Developed in Switzerland, it lets his workshop monitor the vehicle remotely in real time. Engine data, transmission behaviour, even fault codes can be read and reset from home.

“It’s the first one made for the Grenadier,” he said. “Our workshop can watch it live while we’re driving through Iran or the Emirates. It’s a safety net, but also a glimpse of what’s coming for modern overlanding.”

And as for INEOS? He just laughed. “They like what we’re doing, privately. But officially? Nothing. Not even a sticker. That’s fine. Independence cuts both ways.”

Suspension and Stance

The Sheepmaster stands taller than most (other than those fitted with portals). That’s partly because of the prototype rally suspension that’s about to go in. A system worth eight thousand euros, built to take the punishment of high-speed gravel and corrugations. Massive dampers, heavy-duty Eibach springs, and travel figures that will make even seasoned off-roaders raise an eyebrow.

“It’s only been fitted once before,” Thomas said. “We’ll be the first to test it properly. Expect about seven centimetres lift, maybe more once it settles.”

The Invictus alloy wheels, flown in from the US, complete the stance. Ultra-light but rated to carry fifteen hundred kilos each, they feature integrated air-release valves and the sort of machining you usually see on aerospace parts.

Beneath, the belly is armoured in 12mm aluminium—doubled to 24mm in impact zones. The Black Sheep rock sliders and stainless mid-plates are designed to take abuse without complaint.

“If something breaks, we can unbolt and replace it,” he said. “So far, nothing has.”

Up front, a removable Australian bull bar is on its way. If it arrives in time, it’ll be a bolt-on accessory — something travellers can mount for expeditions and remove for legality on European roads. A factory winch sits ready behind the bumper, because if you’re travelling solo, you plan for self-recovery, not rescue.

Insulation, Safety, and the Subtle Stuff

Inside the box, the walls are 30mm insulated panels covered with felt … warm to the touch, soft enough to turn aluminium into something habitable. Hidden behind the side-mounted Maxtrax are concealed windows, invisible from outside. Security sits high on the priority list, especially when you’re parked up far from civilisation.

Even the door locks are unconventional. Some are the kind you’d find on a gun safe rather than a camper. “You can’t stop everyone,” he said, “but you can slow them down.”

There’s a quiet logic to it all. Not paranoia, just preparedness. When you’ve spent months building a home on wheels, you don’t want it broken into for a packet of biscuits and a phone charger.

Boxes That Build Themselves

At the back of the cabin, the furniture is almost non-existent, by design. Instead of plywood or composite cabinetry, Thomas uses Tradom (formerly Tread) storage boxes, the heavy-duty polymer crates better known for strapping to roof racks. Three sit side by side, connected so that their lids open in unison. It’s modular, indestructible, and easily replaced.

“They’re overbuilt for off-road use,” he explained. “You can sit on them, sleep on them, throw them off a truck. And they link together, so you can open all three at once. It’s brilliant.”

Black Sheep is now importing the boxes directly, with plans to distribute them across Europe.

“They’re too good to keep to ourselves,” he said. “And soon, Maxtrax will have a European base in Holland, so things will move faster.”

The Man Behind the Metal

There’s a moment in every call with Thomas when the conversation slows, when the technical talk fades and the man behind the metal takes over. You can hear the fatigue in his voice, but also something else: pride.

“It’s chaos,” he admitted. “But it’s good chaos. We’ve got maybe two weeks left. The list keeps changing, but that’s fine. It’s always like this before a big journey.”

He’s not one for corporate polish. There are no slogans, no speeches about brand alignment or marketing reach. What he builds is born from use, not theory. And that’s what makes it worth writing about.

Before we ended the call, I asked if he ever wonders why he does it—the long nights, the deadlines, the endless tinkering. He paused for a moment, then laughed again, the sound of a grinder sparking somewhere behind him.

“Because it’s what we do. We build. We test. We push. And when it’s done—when it all works—that’s the moment that makes it worth it.”

The connection faded, replaced by the steady whirr of the workshop. Somewhere in Cologne, I closed my notebook and smiled. The beast was coming to life—not through hype or sponsorship, but through the sheer will of a man and his team who refuse to settle for “good enough.”

In a few weeks, Sheepmaster Two will roll into Dubai. And when it does, it’ll carry more than just tools and gear. It’ll carry proof that craftsmanship still matters … that true adventure starts not on the road, but in the workshop, long before the dust ever hits the tyres.

Back then, he wasn’t running a company. He was a Swiss carpenter chasing a drunken bet across Asia.

Thomas didn’t begin in a workshop full of CNC machines and laser-cut aluminium. He began on rooftops, hammer in hand, a site foreman shaping timber under Alpine rain. The work was precise, physical, and unforgiving. When something leaked, you couldn’t talk your way out of it—you fixed it. That mindset stayed.

Off-road driving was his escape valve. Spanners at night, trails at the weekend, the satisfying logic of machinery after days of wood and weather. Then came the Indian Ocean tsunami in 2004, a disaster half a world away that would end up redirecting his life.

Thomas and his partner were regular divers in Thailand. After the waves hit, local friends begged visitors not to stay away—tourism was their lifeline. So the couple kept returning year after year, helping the region recover in the only way they could: by being there.

One night the beer and whisky flowed freely and bravado did the rest. Flying with dive gear had become torture. “Next time,” Thomas said, “I’ll pack it in a truck and drive.” Everyone laughed. Four years later, he rolled into Thailand in a home-built overlander, dive kit in the back.

He hadn’t picked a Land Rover, the crowd favourite. Instead he went with a Santana PS-10—the Spanish cousin with more heart than glamour. Cheaper by miles, square-cut, leaf-sprung front and rear. Simple, repairable, honest. He saw the weak points and built around them: pop-top roof, full interior, everything by hand. When others sank into the sofa, Thomas stayed in the workshop.

Then he pointed the bonnet east and just kept going.

The journey that followed was pure, old-school overlanding. Improvised borders, improvised repairs, and a crash course in the physics of weight. The Santana was originally specced for just over three tonnes and ended up well past four. It coped until it didn’t. In Laos the axles lost their sense of geometry. In Mongolia the leaf springs capitulated day in, day out—as many as eleven breaks in just one day. Each time Thomas fixed them in the field and carried on.

He and his partner reached Thailand the hard way and came home the long way: through Pakistan during the war, Syria before it ignited, even an illicit dash into Vietnam. Thirteen months on the road. Seventy-five thousand kilometres. Fifty-six countries.

When they rolled into Bad Kissingen for the Abenteuer & Allrad show a year later, the truck looked every bit of it—scarred, dirty, and alive. The previous summer it had gleamed under the lights; now people came to see what had survived. The answer was clear: the parts that were light, logical, and easy to fix.

Back in Switzerland, the rhythm of construction work resumed, but only briefly. The body was wearing out—discs, back, patience. Thomas could keep earning a wage until something broke for good, or turn his obsession into a living. He chose the latter.

The VW Amarok became his canvas. In those early days the Amarok world was a blank sheet. Toyota’s Hilux owned the numbers, Land Rover the legend. The VW had clean lines, solid bones, and almost no aftermarket. Perfect.

He built what the truck deserved: smart storage, accessories that looked like factory options, not bolt-ons. Everything guided by two rules—keep it functional, keep it light. Each kilo saved was one less failure waiting to happen.

The name came easily. Amarok means “wolf” in an Inuit language. In his own words, Thomas had always felt like the outsider, the black sheep. Accessories for the wolf, made by the black sheep. Black Sheep Innovations—the wolf in sheep’s clothing.

He worked mostly alone, building and testing on his own Amarok, which doubled as prototype and advert. Word spread. Hunters, municipal crews, and travellers saw the difference: practical design that felt engineered, not improvised. Orders followed, and with them a reputation for precision and restraint.

But the industry shifted. VW tied the Amarok to Ford, and the new truck didn’t feel right. The gut said no. Thomas walked away rather than compromise. A brief flirtation with the Isuzu D-Max confirmed what he already knew: he needed a platform that inspired him, not just paid the bills.

Then came the Grenadier.

The first time he saw one, it was surrounded by over-eager students at Bad Kissingen, stumbling through brochures about “heritage.” The presentation was awful, but the bones looked promising. Switzerland later received the first 136 vehicles, and Thomas had contacts in the right yard. Before the official launch he was crawling through one, removing panels, tracing welds, looking for logic.

He found it. Square steel, straightforward design, solid mounting points. Subtle roof bars and airline tracks built in—not decoration but function.

While others tried to shoehorn Land Rover habits onto a new chassis, Thomas followed the Grenadier’s own cues. A roof platform bolted to the factory bars. A fold-out table mounted to the airline track on the rear door. MOLLE carriers tied cleanly into factory fixing points. Every line looked like it belonged.

The reaction was instant. Orders from across Europe and the US flooded in. For 18 months, two men tried to meet global demand from a small Swiss workshop. They couldn’t keep up—but they kept their standards. Customers waited because they trusted the hands behind the metal.

Success brought its own problems. A distributor in the States began copying parts, tariffs rose, margins shrank. For a bigger company it might have been fatal; for Black Sheep it was just another test. They’d learned long ago how to improvise under pressure.

Then, early 2025, came the call from Dubai.


A new 4×4 Expo in the Safari Park, under the shadow of the Burj Khalifa. The easy option was to ship a demo truck and fly. Thomas chose the harder one: drive there, from Switzerland, and make the journey part of the story.

The Quartermaster sits in pieces on the shop floor. Five weeks to go. The goal: lighter, smarter, truer to the Grenadier’s bones. Instead of a heavy camper box, he designed four structural walls, with stiffness coming from the interior fit. The “roof” would be an Intrepid hard-shell tent with the floor cut out and the bed on gas struts—enter from inside, keep the weather out.

Water and air systems sit low in the chassis. Drawers claim the dead space. Nothing added that doesn’t earn its keep.

Partners stepped up with top-tier kit: 4×4 Proyect from Spain supplying Bilstein-based rally suspension, the first set in Europe; wheels from the US with integrated deflators; Osram lamps so new they won’t hit the market until November. For Thomas it felt like Christmas, only louder and greasier.

But the parts list is secondary. The philosophy drives everything: weight is the enemy, clean design wins, and authenticity beats marketing every time. In Dubai, with the desert sun on the paint and the city skyline beyond, the Quartermaster will either look right—or it won’t.

On the map the route seems simple: Switzerland, Romania, Bulgaria, Turkey, then the dream line through Iran, Kuwait, Saudi Arabia, and into the Emirates. If politics shift, there are alternates. Worst case, a ferry from Greece. The plan is flexible because it has to be.

Safety isn’t theatre. Updates will post 48 hours late, never live. Camps are chosen by instinct—if one of the crew feels uneasy, they move on. Nights are spent in the truck; hotels exist for showers and laundry, not stories.

The further east they plan, the more invitations arrive. Off-road clubs in Kuwait, friends in Saudi, all eager to host. Hospitality is genuine but eats time. The key is to reach Turkey fast, then let the Middle East set the pace.

The Quartermaster will be heavy enough to matter but light enough to live. Tools, fluids, and critical spares only. Thomas trusts the vehicle; he knows its quirks. A warning light means conversation, not catastrophe. Cover the dash if you must—but keep moving.

Time constraints mean they will only be driving one way. Black Sheep can only close the workshop for three and a half weeks. Once the show ends, the team will fly home and the Quartermaster will follow in a container, probably to Bremerhaven.

The challenge isn’t the kilometres—it’s the rhythm. Seven thousand of them can be done; the art lies in covering ground without burning out, saying yes to people without losing days, staying loose while the clock keeps ticking. It’s not off-road bravado. It’s logistics, discipline, and a taste for uncertainty.

And when the truck finally rolls into Dubai, dusted but intact, it won’t just be another display piece. It’ll stand as proof that good design and real-world thinking survive the miles.

Thomas calls the trip an Egotrip, but there’s no arrogance in it. It’s about feeding the restlessness that built the company in the first place. Running a small workshop ties you to the phone, the orders, the routine. A long road trip blows the walls out again. New countries, new faces, new sparks of ideas—that’s what keeps him moving.

He’s clear about the philosophy: this is overlanding, not off-roading. The goal is to arrive with the truck intact and your head full of stories. Breaking things for applause never made sense to him. A machine that survives speaks louder than one that dies dramatically.

The Santana taught that lesson. Every failure came from excess weight. Ever since, he’s treated simplicity as survival.

He also trusts the Grenadier. The so-called sensor circus doesn’t scare him. Older trucks overheated and nobody noticed; now the dashboard just tells you. Experience filters the noise.

Risk, he says, is mostly about how you behave. During that first long journey, the most dangerous country wasn’t war-torn Pakistan but peaceful-looking Nepal. Stay small, stay respectful, talk to people, and the road will look after you.

That outlook threads through every weld and line of the Quartermaster. It’s built to go the distance and come home stronger. The Dubai show might be the official destination, but the real story will be written between the borders—one kilometre, one conversation, one idea at a time.

Black Sheep Innovations began because one man couldn’t leave an idea alone. It grew because those ideas worked: light, functional, honest.

Now that same thinking heads east in a Grenadier Quartermaster, chasing the horizon once more.


By the time it sits under the Burj Khalifa, gleaming in the desert light, the journey that made it will already be behind it—written not in press releases, but in dust and distance.

The post Black Sheep to Dubai 2025 – Episode 1 appeared first on overland-europe.

If the INEOS Grenadier is one of the best things to happen to the 4×4 and overlanding markets in recent years, then one of the best things to happen to the Grenadier has to be Black Sheep Innovations.

Thomas Grütter, Black Sheep’s ceo and chief designer, has spent the last couple of years developing new products for INEOS’ first 4×4. If you haven’t come across Black Sheep’s products before, I can assure you that Thomas has a remarkable knack of thinking outside of the box.

I’ll never forget the time I was called over to “see something I would like”. Thomas went on to demonstrate the very first slide-out rear light clusters on his heavily modified Amarok – Rear Light Extensions, as they are correctly termed.

Black Sheep’s product range is exclusive in the sense the company has neither an inch-thick catalogue filled with countless items, nor does it rely on Asian mass production to satisfy customer demand. Thomas has built the Black Sheep brand upon Swiss engineering and 100% local manufacture.

BRAND NEW ACCESSORIES FOR THE GRENADIER

Thomas told me he is directing all of his energy into the brand new range of accessories, specifically designed for the Grenadier, and will be displaying a fully equipped vehicle at this year’s Abenteuer & Allrad in Bad Kissingen.

I have yet to see the Black Sheep Grenadier to be displayed, but I have been assured it will be equipped with:

• Full vinyl wrap
• Raised suspension
• Larger wheels and tyres
• Heavy duty rockslides and optional steps
• 3 different drawer systems for the load area
• Auxiliary heating
• MOLLE system (Modular Lightweight Load-carrying Equipment)
• Spare wheel mount adapter for larger wheels and tyres
• Side mounts for canisters and/or sand planks
• Roof rack system
• Side-mounted folding table
• Road Shower adapter
• Solar system for improved autonomy
• New 180° and 270° awnings from Clevershade
• New stealth radiator grill
• and more …

These new products are not yet on their website, so I will be dedicating individual previews to several of them over the next few days.
