Adventure campervans, manufactured by hand in West Sussex.
Onyx Vans is a small specialist manufacturer. We design, build, and finish a range of adventure campervans on the MAN TGE platform — the three of us, in our own workshop, to a standard built to last.
A manufacturer the size of a workshop.
We build complete adventure campervans on the MAN TGE platform — designed as whole vehicles, engineered around systems that hold up, and finished to a standard you can see and feel. Small enough that the people who design your van are the people who build it. Skilled enough that it’s made to outlast the trips you buy it for.
Everything happens in our West Sussex workshop: the design, the in-house fabrication, the electrical systems, the fit-out, and the final checks. Every van is built to order.
Find the van for how you travel.
Five standard models and one bespoke programme, all on the MAN TGE platform and all built the same way. Open any model for the full picture, or compare them side by side.
Basecamp
The most accessible way in: a modular, pared-back van that hauls through the week and camps at the weekend.
Explore the Basecamp →Summit
The open, easy-to-drive two-berth, for couples and solo travellers who want space and simplicity.
Explore the Summit →Outpost
The family gear-hauler: four berths, four seats, and maximum storage.
Explore the Outpost →Mesa
The family van, with a permanent shower room as standard.
Explore the Mesa →Arroyo
The Summit’s open layout with more room and a full shower room. The top of the standard range.

Designed and built by the same hands
The three of us design your van, build it, and answer your questions for years afterwards. That continuity is the whole point.
Manufacturer-grade systems
Victron electrical and Aquahot heating, specified because they hold up in the conditions that test equipment properly — the same components used in marine and off-grid home installations.
The MAN TGE platform
We build exclusively on the MAN TGE: better to drive than you’d expect, and supported by MAN’s commercial dealer network across the UK and Europe.
Made to order in West Sussex
Every van is built to order in our own workshop, on a four to six month lead time.
“Adventure is an understatement — the Summit goes where other vans (and cars) wouldn’t, which gives you great options.”— Michael L, Summit owner

Built by people who actually use them.
Onyx began with a van Chris and Heather converted in lockdown and weren’t supposed to keep. It funded an engagement ring, and it confirmed what’s now a three-person workshop on a West Sussex farm. We build the vans we’d want to travel in ourselves.
Start with a conversation.
A discovery call is a relaxed 30 minutes to talk through how you travel and which van fits — an honest conversation with the people who’ll build it. We typically have a four to six month lead time, so the sooner you’re in the diary, the better.
