The Renault Trafic is one of the most popular base vehicles for UK campervan conversions, and for good reason. It offers a sweet spot between size and driveability that the larger Relay/Boxer vans cannot match, while providing significantly more space than a Transit Connect or Berlingo.
This guide covers everything you need to build a comfortable, UK-legal campervan from a Renault Trafic on a realistic budget.
Final Verdict
The Renault Trafic is an excellent choice for a budget campervan conversion. It offers the best balance of space, cost, and driveability for UK van life. With a total budget of £6,000-10,000 you can create a comfortable, reliable home on wheels that will last for years.
Recommended starting point: Focus on insulation and electrical first. A warm, dry van with basic cooking is far more usable than a fancy fit-out with cold condensation running down the walls.
Why the Renault Trafic for a Conversion
The Trafic (sold as the Vauxhall Vivaro and Nissan Primastar in its previous generations) is the UK's best-selling medium panel van. Over a million have been sold here, which means the second-hand market is deep and parts are cheap.
Key dimensions:
- L1H1: 4.99m x 1.96m x 1.97m (internal load length 2.53m, height 1.38m)
- L2H2: 5.39m x 1.96m x 1.97m (internal load length 2.93m, height 1.66m)
The L2H2 model is the sweet spot for a camper conversion — long enough for a longitudinal fixed bed (1.88m width allows a double bed across the back), and tall enough to stand up inside if you use a raised roof or pop-top.
Budget Breakdown: £5,000-12,000 Target
A Trafic conversion can be done at several budget levels. Here is what you can expect at each tier:
Budget Build: £5,000-7,000
- Base van: £3,000-4,500 (2010-2016 model, 100-150k miles)
- Insulation: £300 (XPS + wool + vapour barrier)
- Electrical: £500 (100Ah LiFePO4, 100W solar, DC-DC charger)
- Flooring: £150 (ply + vinyl)
- Furniture: £600 (plywood + birch ply)
- Bed: £200 (mattress from IKEA or local foam shop)
- Extras: £250 (curtains, gas stove, water container)
Mid-Range Build: £8,000-12,000
- Base van: £5,000-7,000 (2016-2020 model, 80k miles)
- Adds: diesel heater (£300), 12v fridge (£250), leisure battery with BMS (£400), roof fan (£200), compressor fridge (£300)
Insulation Strategy for the Trafic
The Trafic has the same thermal challenges as any panel van — large metal panels that conduct heat efficiently and create condensation points.
Recommended approach:
- Floor: 25mm XPS foil-backed foam board. The Trafic floor has prominent ribs; fill these with 12mm foam or closed-cell foam strips before laying the main sheet.
- Walls: A combination of 25mm XPS between the ribs and sheep's wool or recycled polyester (Thermawall) for curved sections.
- Ceiling: 25mm XPS or 10mm Armaflex (closed-cell rubber) if you want to preserve headroom. The L2H2 has enough height for 25mm XPS.
- Vapour barrier: Essential. Use 500-gauge polythene sheet or Reflectix taped at every seam. The Trafic is notorious for damp if this step is skipped.
- Wheel arches: These are significant thermal bridges. Use 20mm Armaflex sheet or spray adhesive with closed-cell foam.
Cost: £250-400 depending on materials chosen.
Electrical System: Keep It Simple
For a budget Trafic build, a straightforward electrical system is all you need:
- Battery: 100Ah LiFePO4 (Fogstar or Renogy) — £350-450
- Charging: 20A DC-DC charger (Victron Orion or Renogy) — £120-150
- Solar: 100W portable panel or 160W fixed panel — £100-200
- Fuse box: Blade fuse holder with 6 ways — £20
- Cabling: 16mm² for main runs, 2.5mm² for 12v circuits — £50
If you plan to use an inverter for a laptop or small appliances, a 300W modified sine wave unit costs around £40-60.
Layout Options for the Trafic
Rear Fixed Bed (Transverse) — Best for Couples
A transverse bed across the back uses the full width (1.96m) to create a king-size bed up to 1.85m long. This works for people up to 6ft. The space underneath becomes a generous garage for bikes, water tanks, and storage.
Rear Fixed Bed (Longitudinal) — Best for Tall People
Running the bed lengthways on one side leaves a corridor on the other. This limits bed width to about 70cm (single) but allows a full 1.95m length — ideal if you are over 6ft.
Rock and Roll Bed — Best for Daytime Space
A rock and roll bed folds down into a seat during the day. This is the most space-efficient layout for a Trafic but uses more mechanism weight and typically costs £400-800 for a proper unit.
Essential Gear for a Trafic Campervan
| Item | Budget Pick | Estimate |
|---|---|---|
| Diesel heater | Vevor 5kW | £120 |
| 12v fridge | Alpicool C15 | £180 |
| Roof fan | Maxxair MaxxFan | £200 |
| Gas hob | Campingaz 2-burner | £40 |
| Water container | 20L jerry can | £15 |
| Leisure battery | Fogstar 100Ah LiFePO4 | £380 |
MOT and Insurance Considerations
Once converted, you must tell the DVLA. The Trafic's V5C logbook needs updating to "Motor Caravan (Body Type 27)". This requires:
- Photos of the conversion (bed, sink, storage)
- A completed V627/1 form (now done online through the .gov portal)
Insurance for a DIY Trafic conversion is available from Brentacre, A Plan, AIB, and Comfort Insurance. Expect £400-800/year depending on the declared value.
Real-World Experience
After 641 days living in a Trafic conversion, the key lessons are:
- The L2H2 is worth the extra cost for standing room
- Damp is the number-one killer — vapour barrier is non-negotiable
- The Trafic handles like a car on A-roads, which makes it better for daily driving than a Relay
- Parts are cheap and widely available from Euro Car Parts and GSF
