Looking for a van conversion that comes with a bit of swagger? Nick Harding might have found just the thing for you, in the form of Adria's latest Twin.


How many Twins can you have? That's not a trick question: Adria is offering its van conversions of that name in three layouts for 2019, all in range-topping Supreme spec. 

So there's two 640 models based on the extra-long Fiat Ducato: the rear transverse double bed SPX, and this, the SLB, offering two single beds at the back. 

Both 640s can be had in Plus format, and only the 6m-long 600 SP is offered at Axess budget level. 

Van conversions are where it's at for 2019. You'll want to get out there and find what's best for you and your budget - and, if fixed single beds are your thing, this SLB will make a good yardstick. 

Lounging & dining

Up front, both cab chairs swivel and there's a forward-facing double travel seat - with a swing-out table extension, which can also be used outside.

The interior styling, Onyx, is exclusive to the Supreme models. It's very automotive and helps set this Twin apart.

Overhead lockers have a push-to-open operation and pneumatic stays, while there's a worktop extension that flips up on the left of the kitchen, an overhead locker and a useful rack by the sink.

As with all of its van conversions, Adria includes a bump-stop on the sliding door so it can stay halfway open. Details such as this can be the deal maker.


Kitchen facilities are just a two-ring hob and sink, but perhaps that's realistic given the amount of space, even in an extra-long van conversion.

The 90-litre compressor fridge is to the right of the kitchen unit, and there are soft-close drawers under the hob and sink, and a single overhead locker.


Using Fiat's lengthiest Ducato allows a floorplan with fixed single beds. They're shown above with a cushion between, but that central section can be moved if you need more privacy, or - more likely - you want to fill the space between the bases with luggage. Or you might just like the idea of a walk-through.

Do note, also, the nearside bed is officially only 1.80m (5ft 9in) long, whereas on the offside, it measures a full 1.92m (6ft 3in). Those bases also house a large cupboard and a sizeable wardrobe.


The washroom also makes great use of space. Adria calls the design Duplex - a tambour door rolls back to reveal a countertop basin and swivel-bowl toilet.

The vanity unit has a mirrored door, and there's also an upper-level locker. For showering, the basin bulkhead swings around to create an enclosed area.

THere's no riser bar for the shower, but you can set it so water cascades directly overhead. The opening window is a real benefit, for ventilation and getting rid of condensation.


The Supreme kit level of this van translates into such desirables as a large sunroof over the cab, along with an opening rooflight over the lounge.

There's a minor catch with the pricing, though. You'll need to check for yourselves, but take your pick from Pack 1 (£1820) or Pack 2 (£2590) for some of the upgrades you might already be expecting. Pack 1, for example, has cab air-con, cruise control and passenger airbag.

And then there's the £3060 Luxury Pack. This brings alloy wheels, DAB stereo with sat nav, rear-view camera, spare wheel and holder, and an awning.

Other options include a 150bhp engine (£1560), Comfort-Matic transmission (£1920), leather upholstery (£1360), habitation air-con (£1330), 120W solar panel (£420) and metallic paint (£890, here in Iron Grey).

Realistically, then, you're looking at a price tag well into the £50,000s.

There really is no doubt about it, van conversions are the motorhome sector to watch for the 2019 season. There are plenty of budget offerings coming onto the market, but Adria is definitely pushing the other way with this thoroughly upmarket model. Just check that options list first.
