My Sprinter · XLWB H3That's what I chose to invest in my own high-spec conversion, but every build is different. Whether you're working with a modest budget or planning a premium off-grid setup, the key is knowing where to spend, where to save and which features really matter to you.
Learn how to prioritise the essentials, judge which upgrades are worth it and understand real costs — without copying my spec. Both products are in development.

A private video call about your plans — vehicle, layout, budget priorities, equipment, storage, bed lifts, wheels and suspension, suppliers and lessons learned. Sprinters are my speciality, but much of it helps with similar campervans too.
I share personal build experience — not certified electrical, gas, structural or mechanical engineering advice.
I built my van over two years, researching every detail carefully as I went. I wanted a premium off-grid van built for real family adventures — a lounge, a proper kitchen, a wet room, and an electric bed lift so the three of us don't live on top of each other.
I went with a rear-wheel-drive Mercedes Sprinter XLWB H3 for the space and headroom, brought in specialists where it mattered, and upgraded the exterior and suspension so it copes with the places we actually want to go. I'm not a conversion company — this is my own build, shared honestly.
~£40,000 conversion spend, excluding the base vehicle — my choice, not a requirement.

Check axle loads, tyre load and speed ratings, suspension compatibility, insurance and any legal requirements before changing wheels, tyres, suspension or ride height.

Layout is the decision everything else hangs off. VanSpace 3D lets you drag and drop a van interior in 3D — no design skills needed — before you spend a penny.
Then mock it up in cardboard inside the van before cutting any ply.

Every van is different — adapt the equipment, budget and layout to your own needs.
For me, the Mercedes Sprinter offered the best combination of space, build quality and versatility. It's a proven commercial vehicle with strong aftermarket support and plenty of conversion options. I chose the XLWB H3 for the extra space and height, giving me room for a kitchen, lounge, wet room and electric bed lift. The rear-wheel-drive platform also suited my plans. After researching every option carefully, it was the best fit for what I wanted to build.
Absolutely not. That's approximately what I chose to invest in my own premium conversion, with plenty of optional extras. You can create a great campervan for less depending on your needs, skills and equipment choices. My guide isn't about copying my budget — it's about understanding your options and knowing where to spend and where you can save.
No. My guide is based on my own XLWB H3, but much of the planning, budgeting, layout thinking and component selection applies to other Sprinter wheelbases and roof heights. You'll need to adapt measurements and equipment choices to your particular van.
Yes. Although it's based on my Mercedes Sprinter, many principles are useful for VW Crafter, MAN TGE, Ford Transit, Fiat Ducato and similar conversions. Planning, budgeting, equipment selection and lessons learned are widely relevant, but vehicle-specific measurements and compatibility will vary.
No. I worked with Nohma for specialist electrical design and support. I share the equipment I chose and why, but recommend professional electrical design for your own requirements rather than relying on generic wiring instructions.
Yes. I'll cover the modifications made to my Sprinter, the equipment selected, actual documented costs and my experience using them. Vehicle-specific fitment and compatibility must always be checked.
Yes. I'll share actual documented build costs, the components I selected and supplier information, clearly identifying any figures that are approximate or unavailable.
Yes! I offer one-to-one video calls where we can chat through your plans, budget, layout and equipment choices. I'll share what I've learned from my own Sprinter build to help you make informed decisions. A 60-minute session costs £99.
