Built to go further. Designed to live in.
Nothing missing. Nothing wasted.
Everything in the Summit has been chosen because it works, not because it looks good in a spec sheet.
We’ve spent years working out what you really need from an adventure van — and what you don’t. The result is a campervan that’s calm, considered, and completely uncompromising where it matters: the systems, the materials, and the space to actually live in.
Designed and built in our West Sussex workshop

Tap or hover any feature to read more. The exterior is further down the page.

The sliding bed
A full 1,900 × 1,670mm super king that slides away in seconds to open up the seating area during the day — no lifting, no rearranging. The aluminium frame makes the van feel far more spacious than its wheelbase suggests.

The garage
An 1,100mm-deep rear garage that opens straight through to the front, so there’s no length limit on what you carry. L-track is fitted throughout to secure kit for the drive, with an optional slide-out gear tray if you want it.

Victron electrical
A full Victron off-grid system — 400Ah of LiFePO4 lithium, 400W of solar, a 50A DC/DC charger, a 3kVA inverter and 120A mains charging. The same equipment used in marine and off-grid home installations, managed from a touchscreen that shows everything in real time.

Truma diesel heating
A Truma Combi 6D running entirely from the main fuel tank — warm air throughout the van and hot water, with no gas cylinder to manage or run out of. It is a proven, reliable unit that does the job without fuss. For deep winter, the Aquahot hydronic system with underfloor heating is a very good upgrade.

Kitchen & living
A double induction hob, 75L fridge and stainless sink — a kitchen for people who actually cook. The seating converts from a dinette with removable Lagun table to an L-shaped sofa for the evening.

The shower
An indoor pop-up shower with composting toilet that folds away completely when you’re not using it, rather than dedicating a permanent corner to a bathroom. There’s an outdoor connection at the rear with hot and cold supply, for kit, wetsuits and dogs.

The space
Most MWB campervans give a big share of the van to a fixed shower room. We don’t — so there’s room to spread out, have friends over, keep a dog comfortable, and store kit without living around it.

Storage
There is more storage here than the layout lets on. Deep drawers run under the seating, and aluminium rear overheads designed around packing cubes keep everything organised and within reach. The light finish keeps the van feeling open rather than boxed in.

Furniture & fit-out
Durable HPL — the surface used in commercial kitchens — in a choice of colours, finished with powder-coated aluminium corners that protect the edges where lesser builds wear first.

Molle door panels
Molle-panelled rear doors take clip-in pouches and organisers for the kit you reach for most — first aid, head torch, dog leads — keeping it accessible without using up garage or overhead space.
How the Summit is laid out
A medium wheelbase that lives like something far bigger.



The Summit is at home anywhere you want to take it
The NC500, the Alps, the long weekends.
Built for where you’re going
The Summit’s exterior is designed and fabricated in-house — not bought off a shelf. Every component has been chosen to be useful on the road, not just to look the part in a photograph.
An Onyx roof rack, built in-house
Every Summit leaves the workshop with an Onyx aluminium roof rack — designed and fabricated by us, fitted as standard. There’s room for solar, a rooftop tent or both, with a side ladder for clean access. It’s a big part of the Summit’s profile, and a clear sign this isn’t an off-the-shelf van.
Specified for where you actually go
The photos here show optional upgrades many buyers add — Black Rhino Warlord alloys, Onyx rear carriers, a Fiamma F45 awning. None are in the standard price, but all are available. If you’re weighing a lift kit, tyres or a specific wheel setup, we’ll talk it through on your discovery call.

Tick the upgrades below to build your spec — it’s an estimate, not a quote.
Climate
+
The Summit is fitted with the Truma Combi 6D diesel system as standard. The Aquahot hydronic upgrade adds continuous hot water, two-zone control and underfloor capability; underfloor heating requires the Aquahot upgrade (added automatically). Habitation air conditioning is one option at one price: limited off-grid use on a 12v system, or full off-grid use on a 24v system. If you plan to run it off-grid we’d recommend adding a battery and the 24v upgrade alongside it — both are in Electrical systems below.
| Aquahot hydronic diesel heating — continuous hot water, two-zone control, underfloor capability | £4,000 |

Summit owners tend to judge a van by where it gets them
Most come to us from a smaller van wanting more room, or with enough kit that everything else has to be designed around it.
The Summit is built for people who…
- Are moving up from a Transporter and want the space without moving up to a motorhome
- Wake up at the trailhead instead of driving to it
- Travel with bikes, boards, cameras, or serious outdoor kit
- Carry enough kit that the storage is the reason for the van rather than an afterthought
- Want to spend a week in the Highlands without thinking about power, water, or heating
- Don’t want to compromise on space just because it’s a medium wheelbase van
- Have looked at other converters and found them either overbuilt with things they don’t need, or underbuilt where it actually matters
Whether you’re following the NC500, chasing races across Europe, or just making the most of long weekends — the Summit is the van that keeps up.
Questions worth asking
Which Onyx model is right for me?
+
The Summit is our medium wheelbase two-berth — the most open and easiest to drive, ideal for couples and solo travellers who want space and simplicity. If you want that same open layout with more room and a full shower room, the Arête is the long wheelbase version. If you regularly travel with a family or need to sleep four, the Mesa adds four travelling seats and a permanent shower room, and the Outpost trades the shower room for maximum storage at a lower price. If you’re unsure, come and see them at the workshop — the differences are clearer in person.
What are my shower options on the Summit?
+
The Summit has an indoor pop-up shower cubicle with a composting toilet fitted as standard. The curtain and fittings fold away completely when not in use, which is a meaningful part of why the Summit feels so open for a medium wheelbase campervan — there’s no permanent corner dedicated to a bathroom. When you need it, it’s there. When you don’t, it disappears completely.
There’s also an outdoor shower connection at the rear of the van, with hot water, for rinsing kit, wetsuits and dogs — or for taking a shower with a view.
If a permanent dedicated shower room is important to you, the Arête and the Mesa are both built around one — the Arête as the long wheelbase version of the Summit’s open layout, the Mesa as the family van.
What is a composting toilet and does it smell?
+
A composting toilet separates liquid and solid waste, which is what prevents odour. Used correctly — and they take very little getting used to — a composting toilet in a well-ventilated van is odour-free in normal use. It’s one of those things that sounds more complicated than it is, and most owners stop thinking about it within the first week.
The practical advantages over a cassette toilet are significant: no chemicals, no cassette to empty at a chemical disposal point, and no dependency on campsites. For buyers planning extended off-grid trips in the UK or Europe, that independence matters.
How much off-grid capability does the Summit have — and is it enough?
+
The Summit runs a full Victron off-grid electrical system with 400Ah of LiFePO4 lithium battery capacity, 400W of roof-mounted solar, and a Truma Combi 6D diesel heating system that runs entirely from the main fuel tank. In practical terms, that means three to four days of comfortable use without any solar input, and indefinitely with reasonable sun — which in the UK covers most of the year outside of deep winter.
The heating and hot water run from diesel rather than electricity, so they don’t draw on the battery reserves the way an electric heater would. That’s a significant part of why the electrical system goes as far as it does.
For buyers planning extended travel, full-time use, or running air conditioning, we offer additional battery capacity, a higher-output DC/DC charger, and a full 24v system upgrade. The standard specification handles the vast majority of adventure use without any additions.
What is LiFePO4 and why does it matter?
+
LiFePO4 — lithium iron phosphate — is the battery chemistry used in the Summit’s Victron electrical system. Compared to older lead-acid or AGM batteries, LiFePO4 batteries are significantly lighter, charge faster, last considerably longer, and can be discharged more deeply without damaging the cells. In a campervan context, that means more usable capacity from the same headline figure and a battery bank that will still be performing well a decade from now.
It’s the same chemistry used in high-end marine installations and off-grid home systems — the Summit uses it because it’s simply the best option available, not because it sounds impressive in a specification sheet.
Can I use the Summit in winter?
+
Yes — the Summit is built for year-round use in the UK and Europe. The van is fully insulated throughout, and the fresh and grey water tanks are insulated and heated, so cold weather use is comfortable rather than something you have to manage around.
The Truma Combi 6D diesel heating system runs from the main fuel tank and provides warm air throughout the van along with hot water, so there’s no gas cylinder to run out of on a cold night in Scotland. For buyers who spend extended time in deep winter conditions, the Aquahot hydronic system is available as an upgrade, adding continuous hot water, two-zone control and the option of underfloor heating.
Do I need a special licence to drive the Summit?
+
No. The Summit comes in at around 3,200kg kerb weight, which falls comfortably within the 3,500kg gross vehicle weight limit covered by a standard Category B driving licence. Most buyers won’t need to think about this at all.
For buyers who want to carry more — additional water capacity, heavier kit, or specific equipment — a higher payload option is available. If you’re planning to load the van heavily, it’s worth discussing on your discovery call so we can make sure the specification is right from the start.
If you’re planning to drive in Europe, your UK licence is valid across EU member states.
Can I take the Summit on a ferry or through the Channel Tunnel?
+
Yes. The Summit’s dimensions are within the standard limits for both ferry crossings and the Channel Tunnel. Height is the most common practical consideration — it’s always worth confirming the specific limits when you book. For buyers planning regular European travel, the MAN TGE platform has a significant practical advantage: MAN’s commercial vehicle dealer network covers the UK and Europe comprehensively, so support is available wherever you are.
How do I fit my bikes in the Summit?
+
The rear garage runs 1,100mm deep and opens straight through to the front of the van, so there’s no arbitrary length limit on what you can carry. Most bikes fit comfortably in the garage without modification.
For a cleaner solution, the Onyx rear carriers with Tokul bike racks — suitable for all bikes — keep the garage free for other kit and make loading and unloading considerably easier. If you’re travelling with e-bikes, the garage has a dedicated USB A/C and 240v socket for charging overnight.
The right solution depends on what you ride and how many bikes you’re carrying — worth a conversation if your setup is specific.
Where does my dog go in the Summit?
+
The garage works well for dogs who prefer their own space on the road — there’s enough room for a dog up to lab or collie size comfortably, and the L-track means you can secure a crate properly for the drive. If the garage is full of kit, the seating area gives a dog of that size plenty of room to settle between the seats. Two spaniels would be easy; two German Shepherds would start to feel tight.
The outdoor shower connection at the rear comes into its own after a muddy walk or a beach day — one of those details that sounds minor until the first time you need it.
How much storage is there in the Summit?
+
More than most people expect from a medium wheelbase adventure campervan. The rear garage runs 1,100mm deep and open-through, with L-track fitted throughout for securing kit properly on the move. The rear overhead storage units are designed to work with packing cubes and keep everything organised without making the van feel cluttered. The rear doors are fitted with molle panels as standard — a grid webbing system that accepts compatible pouches and organisers, keeping the things you reach for most immediately accessible without using up garage space.
If you want a more structured approach to the garage, a slide-out gear tray is available as an option.
What does the Summit cost?
+
The Summit starts from £127,500 inc VAT, and that’s a complete van — the Victron electrical system, Truma Combi 6D diesel heating, full kitchen, sliding bed, rear garage, and Onyx roof rack are all included in that price. There’s no stripped-back entry specification designed to make the opening number look lower than it should.
Many buyers add options before their first trip — rear carriers, an awning, upgraded alloys — and those are listed separately with transparent pricing. The standard Summit doesn’t leave anything meaningful out.
What warranty do I get with the Summit?
+
The MAN TGE base vehicle comes with a three-year manufacturer warranty through the MAN dealer network across the UK and Europe. The Onyx build — the furniture, electrical systems, heating, and all fabricated components — is covered by a one-year Onyx warranty. Victron components carry their own manufacturer warranty, which is among the best in the industry.
Every completed build also comes with a free three-month check-up, where we go through the van thoroughly and address anything that needs attention after the first few months of use.
Is the Summit road legal?
+
Yes. Every Summit goes through an Individual Vehicle Approval process and is registered from new as a motorhome — not a panel van conversion. That means it leaves the workshop correctly classified, with all the legal and insurance implications that come with motorhome registration.
If you’d prefer to register the van as a panel van, that option is available and comes with a small discount on the build price. It’s worth understanding the insurance and usage implications of each before you decide — worth a conversation if you’re unsure which is right for you.
Why the MAN TGE over the VW Crafter or Mercedes Sprinter?
+
The MAN TGE isn’t the most familiar choice — most people arrive expecting a Sprinter — but it’s the right platform for what we build, and the reasons are practical.
Against the Sprinter, it’s comparable in quality and capability at a slightly lower base price, which means more of your budget goes into the build rather than the base vehicle.
Against the VW Crafter, the more important difference is support. The MAN TGE is the commercial vehicle version of the same platform, which means it’s backed by MAN’s truck dealer network — service centres across the UK and throughout Europe. For a van you’re taking seriously into remote places, that network matters in a way it doesn’t for a van that stays close to home.
We’ve driven other platforms. We kept coming back to this one.
Is the Summit the right one?
The Summit is our open, compact two-berth. If you want the same open layout with more room and a full shower room, the Arête is the long wheelbase version. And if you need to carry or sleep more than two, the Mesa and Outpost are built for families.
