Best Van for a Campervan Conversion: How to Choose the Right Base Van

So, you’ve decided you want a campervan. Exciting times.

But before you start choosing cupboards, fabrics, solar panels and where the kettle is going to live, there’s one pretty important decision to make: choosing the van itself.

Finding the best van for a campervan conversion isn’t simply about picking your favourite make or buying the biggest van you can afford. The right base van depends on how you want to travel, who is coming with you, what you want to take and where you plan to go.

At Wild River Campers, we always start with one question: how do you actually want to use your campervan?

Start With How You Want to Travel

Before you start scrolling through vans for sale, think about your lifestyle and the adventures you’re planning.

A campervan for a couple heading off for weekends in the Peak District will have very different requirements from a family of four planning long summer road trips. Likewise, someone who spends most nights on campsites may want something completely different from someone planning to travel off-grid.

Think about:

There isn’t one correct answer. What matters is what is important to you.

For us, travelling as a family of three with a dog, having enough room to sit and cook together is really important. A loo is high on our list too because we don’t always stay on campsites.

We also love paddleboarding, so being able to store our boards and kit in the van matters. Your priorities might be completely different, and that’s exactly why the best campervan layouts are designed around the people using them.

What Size Van Is Best for a Campervan Conversion?

Size is one of the biggest decisions you’ll make.

More space sounds wonderful, but a bigger van isn’t automatically better. You also need to consider where you want to drive, park and store it.

Large Vans

Large panel vans give you the most freedom when designing a campervan layout. They can be a great option for families, longer trips and anyone wanting features such as a fixed bed, larger kitchen, toilet, shower or plenty of storage.

Popular large vans for campervan conversions include:

The Citroën Relay, Peugeot Boxer and Fiat Ducato are particularly popular conversion bases because their relatively boxy shape can make planning the interior easier.

Different wheelbases and roof heights mean there is still plenty to consider within each model.

And we’ve worked on all sorts at Wild River Campers — even a Land Rover 101 ambulance — so we know there isn’t just one type of vehicle that can become a great adventure van.

Medium Vans

A medium-sized van can be a brilliant compromise.

Examples include:

They’re generally easier to manoeuvre and park than a large panel van while still offering enough space for a very capable campervan conversion.

For couples, solo travellers and smaller families — particularly those who regularly use campsites or an awning — a medium van can work extremely well.

Small Vans

If you prefer something compact and easy to use every day, don’t discount a small van.

Popular choices include:

A clever small camper conversion can provide sleeping space, storage and basic cooking facilities without feeling like you’re driving a large motorhome.

They’re particularly appealing for solo travellers, couples, weekend escapes and anyone wanting a vehicle that can double as an everyday car or van.

Not Sure What Size You Need? Hire One First

This is something we’d genuinely recommend if you’re unsure.

Hiring a campervan before committing to your own conversion can teach you an enormous amount.

After a few nights away, you’ll quickly discover whether you really need a shower, whether you’d prefer a fixed bed, how much storage you actually use and whether a particular size of van feels comfortable to drive.

You may discover that your must-have feature isn’t nearly as important as you thought — while something you’d barely considered suddenly becomes essential.

It’s a great way to experience campervan life without ownership before investing in your own build.

Check the Mechanical Condition Before You Buy

It’s easy to get carried away imagining what the inside of a van could become, but don’t forget what you’re actually buying underneath it all.

A beautiful campervan conversion built into a van with serious mechanical or structural problems can become a very expensive headache.

Look for a van that has been properly maintained and, where possible, check its service and MOT history.

Things worth investigating include:

If you’re not mechanically minded, take someone knowledgeable with you or consider arranging an independent pre-purchase inspection.

Spending money checking the vehicle before buying it could save considerably more later.

Always Test Drive the Van

Never underestimate the value of a proper test drive.

You’re not only checking whether the van drives correctly. You’re also discovering whether you actually like driving it.

Think about visibility, seating position, steering, braking, engine performance and how comfortable you feel manoeuvring it.

Remember that once the campervan conversion is complete, you could spend many hours behind the wheel travelling to your next adventure.

If something doesn’t feel right before you’ve even converted it, pay attention to that feeling.

Think About Your Campervan Layout Before Buying the Van

You don’t need every cupboard planned before buying your base vehicle, but having a rough idea of your ideal campervan layout can prevent expensive compromises later.

Think about sleeping arrangements first.

Would you like a permanent fixed bed that is always ready to climb into? Or would you rather have seating during the day that converts into a bed at night?

Then consider your kitchen.

If you love cooking, you’ll probably appreciate decent preparation space, storage and a practical fridge. If you’re happier with simple meals and eating out, you may prefer to devote that space to something else.

Then there’s the bathroom question.

Some people won’t travel without an indoor toilet and shower. Others would much rather use the space for storage and rely on campsites.

Neither approach is wrong.

That’s the beauty of a bespoke campervan conversion: it should work around the way you travel rather than forcing you to adapt to somebody else’s idea of the perfect van.

Don’t Forget Payload and Weight

One thing that’s easily overlooked when dreaming about your finished campervan is weight.

Everything you add contributes to the finished vehicle weight: furniture, batteries, water tanks, solar equipment, heating, cooking equipment, bikes, paddleboards, luggage, passengers — even the water you’re carrying.

That makes the base vehicle’s weight and payload an important consideration from the beginning.

A beautiful layout isn’t much use if the finished campervan can’t safely carry the people and equipment you bought it for.

Set a Realistic Campervan Conversion Budget

Your budget needs to cover more than buying the van and making the interior look lovely.

Depending on your conversion, you may also need to budget for things such as:

It’s very easy to get distracted by the Instagram-worthy finishes, but a campervan needs to work properly first.

Comfort, reliability, sensible storage and a well-planned electrical and water system aren’t always the glamorous bits you photograph, but they’re the things you’ll appreciate when you’re actually away in the van.

At Wild River Campers, our approach is to understand how you want to travel and design the conversion around your lifestyle and budget.

Remember the Practical and Legal Side of a Conversion

If you’re planning significant changes to a vehicle, it’s also important to understand the relevant DVLA requirements and make sure your conversion remains safe and roadworthy.

Don’t choose your base van solely around whether you think it can eventually be described as a motor caravan on the V5C. Think first about whether it is safe, suitable and capable of supporting the conversion you want.

It’s worth checking the latest GOV.UK guidance before starting your build, particularly if you’re making structural changes or changing details that appear on the vehicle’s V5C.

So, What Is the Best Van for a Campervan Conversion?

The best van for a campervan conversion is the one that fits your life.

For one person, that might be a compact Caddy that can disappear into a normal parking space.

For another, it’s a long-wheelbase panel van with enough room for the family, dog, paddleboards, kitchen and a proper toilet.

Before you buy, think beyond the van itself.

Picture arriving somewhere beautiful after a long drive. Where will everyone sit? Where will you cook? Where will all the wet coats go? Can you get to the bed without rearranging half the van? Where’s the dog going to sleep?

Those everyday details are what turn a van into a campervan you genuinely enjoy using.

And if you’re still unsure, that’s where we can help.

At Wild River Campers, we create bespoke campervan conversions designed around real people, real adventures and the way you want to travel. From choosing a practical layout to creating comfortable, reliable living spaces, we’ll help you build a campervan that feels like yours.
