Is the Adria Twin Supreme 640 SLB a practical luxury campervan?
The Adria Twin Supreme 640 SLB is a premium 6.36m campervan built on the Fiat Ducato chassis. It is designed for up to three people, featuring a sought-after rear twin bed layout and a 3500kg MTPLM. Its defining features include the panoramic Sky-roof and a space-saving Duplex bathroom, balancing high-end interior comfort with the agility of a van conversion.
- Rear longitudinal twin beds featuring high-quality mattresses for improved accessibility.
- Signature panoramic Sky-roof and cabin-loft design to increase natural light.
- Innovative Duplex bathroom with a rotating wall to create a dry shower cubicle.
- Kitchen equipped with an 84L compressor fridge and integrated storage solutions.

Buying an Adria Twin Supreme 640 SLB
Who it suits
- Couples seeking the comfort of permanent longitudinal beds without a full-sized motorhome.
- Year-round tourers who require the diesel heating and insulation provided by Adria.
Reasons to consider it
- The Sky-roof provides significantly more natural light than standard van conversions.
- The 485kg payload is competitive for a 3500kg MTPLM vehicle of this length.
- Longitudinal beds avoid the need for one occupant to climb over another at night.
What to check
- Verify the remaining payload after any dealer-fitted extras like awnings.
- Test the rotating wall in the Duplex bathroom for smooth operation.
- Ensure the 6.36m length is compatible with your intended storage or driveway space.
Worth knowing: Confirm the specific engine and gearbox fitted, as these vary across the price range. Check if the optional sliding door flyscreen is included in the specific vehicle price.
Compare the Adria Twin Supreme 640 SLB with similar models
| Model | Berths | Maximum weight | Length | Typical price |
|---|---|---|---|---|
| Adria Twin Supreme 640 SLB | 3 | 3500 kg | 6.36 m | £58,000 to £82,000 |

The Adria Twin Supreme 640 SLB sits at the top of the Twin range, offering a premium 6.36m longitudinal bed layout. While it shares the 3500kg MTPLM and Fiat chassis with other 640 variants like the SGX and SPB, the SLB focuses on bed accessibility. It commands a higher price point than the shorter 600 SPB models, trading compact parking for increased internal living space and a more open cabin-loft feel.
Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.
Ownership and Maintenance Tips
- Utilise the dimmable LED zones to manage power consumption when off-grid.
- Regularly clean the panoramic Sky-roof to maintain the interior light levels.
- Monitor the 84L compressor fridge power draw during extended stays without hook-up.
Common mistakes to avoid
- Assuming the 6.36m length will fit in all standard supermarket parking spaces.
- Overloading the rear storage area without calculating the impact on the 485kg payload.
Worth knowing: Always verify the exact weight of added accessories to stay within the 3500kg limit.
