The Adria Twin Supreme 600 SX

The Twin was the original fixed bed campervan but any sense of it being unique was lost long ago. This is now one of the most crowded sectors in the motorhome market, with offerings from all the main European manufacturers, as well as campervan specialists.

But Slovenian firm, Adria, has not sat back on its laurels, adding multiple variants on the Twin theme over the years. The latest is this 600 SX, in upmarket Supreme spec.

The bed

It’s still a six-metre Fiat Ducato with a rear transverse double bed but there’s plenty to mark out the latest model. So, let’s start with the bedroom, which features an electric bed that rises and falls on seatbelt-style straps.

The mattress (on a slatted base) measures 1.94m (a good length, making the most of the Fiat’s shape) by 1.41m, but the surprise is how low it is – at just 580mm off the floor, access is super-easy.

However, you can also press a button and raise the bed right up to the ceiling, leaving 1.54m headroom below and a huge space in which to stow gear.

You could even, possibly, use the fixed offside section of the bed as a mini-sofa. More importantly, there’s a tall locker on the nearside with sliding doors, so you can reach your clothes whether the bed is up or down.

Feet will go under that tall cupboard at night but, on the offside, the overhead locker is high up, so it won’t stop you sitting up in bed and using the mini reading lights provided. Two USB ports are fitted, too.

The interior

So, the Twin’s bedroom is as versatile as any, but it’s up front where the 600 SX is in a league of its own. Here, it’s the optional Sunroof XL that will grab your attention. Filling almost all of the roof above the lounge area, this vast opening panel is joined by a fixed overcab sunroof to flood the interior with daylight and transform the feeling of space.

The actual layout might be conventional but the details are well thought out. The rear bench is comfortably shaped and has automotive head restraints, while the table has another car-like touch – recessed cup holders.

You can also use the table outside, clipped to the back of the kitchen cabinet.

The kitchen

Overhead lockers extend into the cab, where there’s a full-height walk-through and the same clean simple lines with handleless lockers feature in the galley. Here, the worktop extension flap (adjacent to the door) is as expected but its mechanism is of superior quality. Everything, in fact, gives off an impression of durability.

A kitchen unit that narrows slightly towards the front also increases the feeling of space in the aisle, while the super-generous kitchen drawers create plenty of practical stowage.

At counter level, split glass lids reveal a combination sink and hob unit from Can, with one high-speed burner on the cooker.

Alongside the sink, the Thetford compressor fridge is mounted at waist height for convenience and has an 84-litre capacity.

The washroom

The washroom in this model is not new but it didn’t need updating. It includes a swivel cassette toilet, bowl-on-a-plinth-style washbasin, an opening window and a drying rail for towels or wet clothes. Then, when you want to shower, the curved wall behind the basin rotates over the loo to create a good-sized space for a hose down.

There are two small outlets in the shower tray and the whole design feels built to last, with no flimsy plastic catches.

A final plus point in the newest Twin’s favour is the installation of Truma’s Combi boiler and blown-air heating in diesel-powered form, while the fresh water tank holds a respectable 100 litres.
