Expert reviews and walkthroughs of the Bailey Twin Supreme 600 Spb Fiat Campervan
More videosThe Adria Twin Supreme 600 SPB, built on the reliable Fiat Ducato chassis, is a multi-award-winning campervan renowned for its luxurious van conversion. Its innovative 'Sky-roof' and open-plan 'Cabin-loft' design redefine interior spaciousness, banishing the 'boxy' feel often found in traditional campervans. This model's 600 SPB configuration cleverly incorporates a rear transverse bed, optimising living space within its sub-6-metre length, making it exceptionally easy to manoeuvre through narrow UK country lanes and urban environments.
Inside, the Twin Supreme offers a boutique hotel experience with high-end 'Onyx' textile finishes and sophisticated dimmable LED lighting. The kitchen is highly functional with a large compressor fridge, while the innovative 'Duplex' bathroom features a swivelling wall to create a separate shower cubicle. Whether you are a solo traveller or a couple seeking a premium touring experience, this campervan delivers uncompromising quality and modern European style.

The Adria Twin Supreme 600 SPB is a refined van conversion measuring 5.99m in length, built on the Fiat Ducato chassis. It is designed for two to three people, featuring a rear transverse bed and a 3500kg MTPLM. The model is distinguished by its Sky-roof and Cabin-loft design, which increases interior light and perceived space, alongside a functional Duplex bathroom with a swivelling wall. With a payload of 565kg, it balances luxury finishes like Onyx textiles with practical touring capabilities.
Worth knowing: The transverse bed layout requires one occupant to climb over the other to exit the bed. Internal storage is more restricted than in larger coachbuilt motorhome alternatives.
Worth knowing: Pricing varies significantly between 58000 and 79500 depending on the specific year and equipment level. The 2.05m width is standard for van conversions but narrower than coachbuilt models.
| Model | Berths | Maximum weight | Length | Typical price |
|---|---|---|---|---|
| Bailey Twin Supreme 600 Spb Fiat Campervan | 3 | 3500 kg | 5.99 m | £58,000 to £79,500 |
| Adria Twin Supreme 600 SPB 140BHP Auto | 3 | 3500 kg | 5.99 m | £62,000 to £84,000 |
| Elddis Signature CV40 | 3 | 3500 kg | 5.99 m | £48,000 to £68,000 |
The Adria Twin Supreme 600 SPB occupies a premium position in the van conversion market, priced between 58000 and 79500. While it shares the 5.99m Fiat Ducato foundation with rivals like the Swift Carrera 144 and Elddis Signature CV40, it distinguishes itself through the specific Duplex bathroom and Sky-roof architecture. Buyers must weigh the high-end interior finishes and innovative space-saving features against the inherent limitations of a transverse bed layout found in this 3500kg MTPLM class.
Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.
Worth knowing: Payload calculations should include all passengers and water to stay within the 3500kg MTPLM.
This variant offers a similar 5.99m length and 3500kg MTPLM but includes an automatic gearbox for those preferring two-pedal driving.
