How to choose the right vehicle to convert
Whether you’re building a simple weekend van or a long-haul home on wheels, the very first step is the same: Choose the right van to convert.
A van conversion takes time, money, and energy, so the better your base vehicle fits your real life, the easier everything becomes later. And the fun part? Vans come in every flavour: tall, short, wide, narrow, stealthy, eye-catching, functional, rusty, cheap, expensive… Finding the “right one” is genuinely exciting.
Let’s explore how to pick the best van for your campervan conversion, without ending up with a build that looks great online but doesn’t work in real life.

Before you start browsing vans: Check the boring stuff first
Before you go deep into listings and YouTube comparisons, pause for two admin checks that can save you a painful mistake. Rules and insurance requirements vary across Europe. In some countries you may run into:
- Minimum interior height requirements (for example around 1.80 m in some categories)
- Insurance companies that won’t cover certain conversions (e.g., some ex-buses or unusual vehicle types)
- Tax, parking or evan toll differences once your vehicle goes above 3.5 tonnes (weight classes matter)
The point is simple: don’t buy a van and assume you can convert it. Check first.
Do this before you buy anything
- Check local conversion rules for your country (and your vehicle category).
- Call your insurance company and ask directly about coverage for converted vans. If possible, reference an already-converted van of the same model to understand typical pricing and what’s covered for accidents/theft. If you’re unsure, call again. It’s worth it.
Once these basics are clear, you can start your van hunt with confidence.
4 Key Questions Before You Choose Your Base Vehicle
What’s your actual goal with vanlife?
Before you fall in love with a listing, get clear on what you’re building for.
Are you chasing spontaneous weekends in the woods, or a six-month road trip across Europe? Your goal affects everything: the van size, the layout, how much power you’ll need, even how many solar panels make sense on the roof.
A helpful first step is to write down your “must-haves” and “nice-to-haves”:
- What do you want in your conversion?
- What can you live without?
- How much space will your essentials take?
If you want a structured base for this, use a simple checklist like a Van Conversion Map (rooms/zones, storage, electrics, water, sleeping, work space).t
Quick tips to avoid common buying mistakes
Buying a campervan base vehicle is like choosing a travel partner: you want someone reliable, not just good-looking.
A few quick “save-your-future-self” tips:
- The cheaper the van, the more you need to budget for repairs and downtime
- Don’t buy on vibes. Buy on fit + condition
- Don’t assume you can “fix it later” if the base vehicle is the wrong size
What type of van fits you best?
Do you want a comfortable “mini-motorhome” with all the features, or are you more of a minimalist who’s happy with the essentials?
This matters because your base vehicle sets your limits:
- Standing height
- Bed orientation (lengthways vs sideways)
- Bathroom options (or no bathroom)
- Storage volume
- Stealth vs obvious camper look
We’ll guide you through the main van options, but you’ll get a better result if you decide early whether you’re building:
- A full-time live-in van, or
- A stealthy city-friendly weekend van, or
- A family / long-distance road trip van
Activate your inner car dealer
Prepare to ask questions, negotiate calmly, and walk away if something feels off. Most beginners lose money here, not because they’re bad at bargaining, but because they get emotionally attached too early.
You don’t need to be aggressive. You just need to be prepared.
Define Your Requirements (With Real-Life Scenarios)
We suggest writing down all your requirements for the conversion. What are your ‘must-haves’, and what can you manage without? How much space will everything take up? Having a clear picture of what you want will help you choose the right type of van for the conversion.
Stealth mode: Blend in inside cities
If you spend time in cities, maybe you even work a normal job and just travel on weekends, a stealth campervan can be a real advantage.
For our first Europe trip we chose a Renault Trafic specifically to park discreetly in cities. A more subtle van can:
- Reduce attention
- Make overnight parking easier
- Lower the risk of being moved on by locals/police
But here’s the downside we learned the hard way: a stealth campervan can also look like a trades van, the kind people assume is full of tools. We experienced this ourselves, unfortunately.
Stealth is great, but it’s not “zero risk”. It’s just a different type of risk.
Full-time vanlife: Standing height matters more than you think
If you plan to live in your van full-time, interior height becomes a daily quality-of-life thing. Being able to stand up:
- improves posture
- makes cooking and dressing easier
- reduces the “cramped box” feeling in bad weather
If you are able to, choose a high-roof option. The extra height is worth it.
Travelling with a partner?
Two people changes everything. The big one: bed width and length.
After a long day (or a fun night out), the last thing you want is sleeping curled up because your bed is too short or too narrow. A slightly longer/wider van can dramatically improve sleep, which improves everything else.
Weather: Where will you actually travel?
If you travel in cold or rainy places, you’ll spend more time inside. That means you want:
- Enough space to move
- A comfortable layout
- Ventilation that prevents condensation
And if you travel in proper cold climates (like we do), remember:
- Insulate floor and ceiling more, witch reduces interior height
- So if winter travel is part of your plan, consider a van with extra headroom.
Requirements Checklist
We suggest writing down all your requirements for the conversion. What are your ‘must-haves’, and what can you manage without? How much space will everything take up? Having a clear picture of what you want will help you choose the right type of van for the conversion. You can use the ‘Van Conversion Map’ as a basis for your checklist.
Imagine the disappointment of buying a van only to discover that you cannot convert it! Therefore, do this first:
Contact your insurance provider:
It is helpful to refer to an already converted van of the same model to get a better understanding of the premium and what is covered in the event of an accident or break-in. Don’t hesitate to call them if you are unsure.
Check laws and regulations:
Review the laws, regulations, and requirements set for conversions in the Europe. This includes checking local guidelines like DVLA guidelines for reclassifying a vehicle as a motor caravan and ensuring compliance with gas and electrical safety standards (such as Gas Safe and BS EN standards).
What’s your budget?
Let’s not pretend: Convert a can into a fullfunctionall campervan can get expensive. So here are our recomandations to budget your conversion and estimate your campervan buildning cost.
A simple depreciation rule of thumb
A rough guideline many builders use is:
try to spend around half the van’s purchase price on the conversion.
Why? Because the more mileage you add, the more the vehicle depreciates and it’s painful to over-invest in a base van that won’t hold value.
Example, approximate:
- If you buy a van for €10,500, try to keep the conversion around €4,500–€6,500.
This isn’t a law, it’s a sanity check. Some builds justify more spend. But for many first-time builds, it prevents the classic trap: “I built something amazing and financially it made no sense.”
Estimate your build cost, the practical way
Make a list of everything you need and price it out. Then add +30% for unexpected expenses.
That becomes your conversion budget.
At the end of this series we’ll also share a complete “van conversion essentials” list to help you plan faster.
Don’t forget the non-build costs
Building is one thing, getting road-legal and running is another. Depending on your country, don’t forget:
- road tax / environmental fees
- insurance
- inspection / registration checks
- potential weight-related costs (especially near 3.5 tonnes)
These can add a surprising amount to your total.
Choosing Your Van (So the Build Is Actually Enjoyable)
Now that you’ve thought through requirements and budget, it’s time to decide what type of vehicle fits best.
My personal top pick is the Mercedes Sprinter (even though we currently have a Renault Trafic). The Sprinter is reliable, well-built and comfortable , but it often costs more upfront.
A better way to choose than “brand loyalty” is to decide based on:
- Your desired interior height
- The bed layout you want
- How much storage your life requires
- Where you’ll travel (cities vs remote, summer vs winter)
In the next parts of this series, we’ll break down van sizes and layouts in a way that’s easy to compare.
Lifestyle Fit:
Don’t Forget How You’ll Use the Van
Activities and hobbies
Think about what you want space for:
- Bikes (inside garage vs rear rack)
- Surfboards (roof storage)
- Climbing gear, hiking kit, skis
This determines storage solutions and can influence which van length/height makes sense.
Working while travelling
If you’ll work on the road, plan for:
- Internet (mobile hotspot, data plan, maybe a roof antenna later)
- A dedicated workspace (fold-out desk, swivel table, or dinette setup)
- Enough power outlets and charging options
Systems and Equipment
Power: solar and electrical system
A self-sufficient van needs a reliable power setup. If you plan to run laptops, fridge, fans, charging, and maybe an inverter:
Choosing a van with the right roof area and interior space makes this easier.
Water and waste
If you want a proper water setup:
- Fresh water tank (or jerry cans)
- Waterpump
- Filtration (optional but nice)
- Grey water plan
- Toilet option (portable or built-in)
These systems take more space than most beginners expect , especially if you want it tidy and easy to maintain.
Safety and Maintenance (The Unsexy Stuff That Saves Trips)
Safety basics
At minimum, consider:
- smoke alarm
- Carbon monoxide alarm
- Fire extinguisher
- Secure storage and additional locks
- Optional cameras/alarm for peace of mind
Maintenance and repairs
Regular maintenance keeps your van reliable and prevents expensive surprises. Learn the basics:
simple troubleshooting
Keep a small tool kit and a few spare parts so minor issues don’t end your trip.
- Tyre checks
- Oil level
Comfort and Design (Where Vanlife Becomes “Nice”)
Insulation and climate control
Good insulation isn’t just for winter, it improves comfort year-round.
Common comfort upgrades:
- insulating floor, walls and ceiling properly
- ventilation (roof vent / fan helps prevent condensation)
- diesel heater if you travel in colder seasons
A van with a higher roof makes insulation less “costly” in terms of lost headroom.
Custom furniture and storage
To maximise space:
- use every corner
- build multifunctional furniture (beds with storage, fold-out tables)
- design storage based on what you actually carry
The best builds are the ones that feel effortless to live in.
