About the Adria Twin Supreme 640 SLB
The Adria Twin Supreme 640 SLB stands out as a premium campervan, setting a high benchmark for luxurious van conversions. Constructed on the dependable Fiat Ducato chassis, its defining characteristic is the iconic ‘Sky-roof’ panoramic window. This floods the contemporary interior with natural light, creating an unparalleled sense of spaciousness, perfect for enjoying views from the Scottish Highlands to the Cornish coast. The SLB layout is particularly sought-after for its rear longitudinal twin beds, which offer easy access and high-quality mattresses for a truly restful night.
Adria's meticulous attention to detail is evident throughout the interior. The ‘cabin-loft’ open-plan design enhances the airy feel, complemented by the innovative ‘Duplex’ bathroom. This clever feature boasts a rotating wall, allowing you to switch seamlessly between a practical washroom and a dry shower cubicle. The well-appointed kitchen, featuring a compressor fridge and generous storage, makes this model ideal for extended tours. This campervan expertly balances agility for navigating narrow country lanes with the comforts typically found in much larger motorhomes.

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.
- Winterised for UK use with Webasto diesel heating and an insulated waste tank.
Worth knowing: The 6.36m length exceeds standard UK parking bay dimensions. Payload capacity of 485kg reduces quickly when adding heavy optional accessories. Pricing reaches the upper end of the Twin range, reflecting the Supreme specification.
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 |
| Adria Twin Supreme 640 SLB 140BHP Auto | 3 | 3500 kg | 6.36 m | £58,000 to £86,000 |
| Adria Twin Supreme 640 SGX | 3 | 3500 kg | 6.36 m | £58,000 to £85,000 |
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.
Alternatives to the Adria Twin Supreme 640 SLB
This variant offers the same 6.36m length and 3500kg MTPLM but includes an automatic gearbox for those prioritising driving ease.
