Choosing the best base van for your camper conversion
The “best” van depends on what you want to build: a compact day-van, a weekend tourer, or a full-size off-grid camper. Think about three things first:
- Size: do you need standing room and a bathroom, or something compact and easy to park?
- Payload: heavier builds need more carrying capacity
- Parts/support: common vans are easier to service and insure
Most popular base vans in the UK (why people choose them)
These are some of the most common choices for UK conversions, used by many converters and DIY builders:
- VW Transporter (iconic, compact, huge community)
- Ford Transit Custom (great all-rounder, widely supported)
- Fiat Ducato / Peugeot Boxer / Citroën Relay (boxy shape = space efficient)
- VW Crafter / MAN TGE (more space, modern feel)
- Mercedes Sprinter (big builds, premium option)
Quick guide to van sizes (what you can fit)
Small/medium vans: best for day vans and simple touring layouts (easy to park, cheaper to run).
Large panel vans: best if you want proper zones (bed + kitchen + storage) and more off-grid capability.
Extra-long/high roof: better if you want maximum storage, a fixed bed, or a wet-room style setup.
What to check before buying a base van
Rust/structural condition (especially around arches and sills)
Service history
Mileage vs maintenance
Payload rating and whether your build will be heavy
