When it comes to campervan conversions, selecting the right base vehicle is key.
With so many factors to consider—from interior space and layout flexibility to payload capacity and vehicle history—this is a specialist area where we are able to guide you through the process.
At SSL Conversions, our expertise means you can benefit from Liam and the teams’ knowledge and expertise every step of the way. Before you start your journey with us, here are some top tips to begin thinking about.
We consistently recommend three models: the Citroën Relay, Peugeot Boxer, and Fiat Ducato. Despite their different branding, these vehicles share an identical chassis and dimensions, offering the best platform for conversion if spaciousness is high on your list of requirements. The Mercedes Sprinter and Volkswagen Crafter are also popular choices. However, the three models we recommend are superior in some key areas.
Key Differences:
Why The Citroën Relay, Peugeot Boxer, and Fiat Ducato?


While many social media videos highlight the Sprinter’s interior space (often using fish-eye lenses to exaggerate the roominess), the reality is that the Relay/Boxer/Ducato models deliver practical, generous space without trickery.
Choosing a base vehicle isn’t just about the model—it’s also about its history. Here are the key points we always advise you focus on:
Go for a Gentle Life: Look for vans with one or two previous owners and a low-stress history. Vans used by smaller companies or tradespeople like plumbers or electricians are often preferable to those used by larger, heavy-duty operations.
Service, Previous owners and Mileage: Fewer owners, lower mileage and a full service history not only give a good indication of a robust vehicle but also protect your asset’s resale value.
Take an expert along: it may be a good idea to bring someone knowledgeable along or have a trusted organization like AA or RAC perform a pre-purchase check. They will charge for this service but if it helps you avoid issues down the road it is a wise investment.
Do your research: A quick Google search for reviews can save you from potential headaches later. A reputable dealer with verified reviews is a must for peace of mind. If a dealer has a limited online presence it is worth avoiding them – even if the vehicle on offer ticks all the boxes.
Converting a van into a camper is an exciting project, but it involves many specialist considerations and potential pitfalls. From choosing a vehicle with the right dimensions and history to ensuring that your payload and legal requirements are met, every detail matters.

Our expert guidance means that you can focus on the joy of creating your perfect home on wheels, confident that every risk is managed professionally, and we will support you whichever make of base vehicle you feel is right for you.
