Practical ownership tips

Payload capacity

A versatile garage-focused campervan for two to three people.
The Adria Twin Supreme 640 SGX is a 6.36m campervan built on the Fiat Ducato chassis, distinguished by its rear electric lifting bed which creates a large garage space. It features a front dinette and a duplex bathroom, accommodating between 2 and 3 berths with a payload of 510kg.

- Signature sky-roof and panoramic window for natural lighting.
- Duplex bathroom design featuring a swivelling shower wall.
- Built on the Fiat Ducato chassis with a 6.36m total length.

Buying an Adria Twin Supreme 640 SGX
Who it suits
- • Outdoor enthusiasts needing to store mountain bikes or large gear internally.
- • Couples seeking a high-specification interior with a panoramic sky-roof.
Reasons to consider it
- • The 510kg payload is substantial for a 3500kg MTPLM van conversion.
- • The rear longitudinal bed layout provides residential-style sleeping comfort.
- • Integrated compressor fridge offers efficient cooling for off-grid use.
What to check
- • Verify the specific engine and transmission fitted as prices range from 58000 to 85000.
- • Inspect the Onyx interior materials for wear in high-traffic areas.
- • Test the swivelling wall in the duplex bathroom for smooth movement.
Worth knowing: Confirm if specific optional equipment requires a C1 driving licence due to weight. Check the operation of the electric bed mechanism during viewing.

| Model | Berths | Maximum weight | Length | Typical price |
|---|---|---|---|---|
| Adria Twin Supreme 640 SGX | 3 | 3500 kg | 6.36 m | £58,000 to £85,000 |

The Adria Twin Supreme 640 SGX occupies a specific niche in the 6.36m van conversion market, balancing a 3500kg MTPLM with a high-utility garage. While alternatives like the Pilote V630J Evidence or Carado CV640 Pro+ offer similar lengths and berth counts, the Adria is defined by its electric lifting bed and signature panoramic sky-roof. Potential buyers must weigh the premium price range against the unique storage flexibility provided by the SGX layout.
Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.
Ownership and Maintenance Tips
- Utilise the 510kg payload carefully when installing additional accessories.
- Regularly clean the panoramic sky-roof to maintain the interior light levels.
- Familiarise yourself with the Fiat Ducato safety assistance systems for long journeys.
Common mistakes to avoid
- • Attempting to park in standard city bays without accounting for the 6.36m length.
- • Neglecting to secure heavy items in the garage before operating the lifting bed.
Worth knowing: Ensure the rear garage is not overloaded beyond the 510kg total payload limit.
