How can you improve on what is an already popular product? Adria’s Fiat-based Twin van conversions have proved bestsellers since they were first introduced at the beginning of this century.

But with continuing supply issues at Fiat, and the trend among other brands to start producing more upmarket van conversion ranges, it seemed inevitable that Adria, which you can find out more about in our best motorhome manufacturer guide, would do the same.

The Twin Max, on a MAN base vehicle (at 6.84m, nearly half a metre longer than the extra-long-wheelbase Fiat), is the impressive result.

The Adria Twin Max 680 SGX model I reviewed here, with a long rising bed in the rear, also nods to another trend, with some of the best camper vans now designed to help people pursue other hobbies, as I shall explain.

The van as standard has an MTPLM of 3500kg, but all UK-imported models come with the MAN Lux Pack. Including that bumps up the price by £13,710, taking the overall cost into six figures. It also means you’ll need a C1 licence to drive a ‘van which we shortlisted at the Practical Motorhome Awards 2024 for the most innovative motorhome category.

On the plus side, the payload rises from 400kg – quite meagre, even for two, especially if you intend to bring heavy sports gear along – to a much more reasonable 900kg.

I thought it was a rather austere cab as I climbed into it, but that Lux Pack adds a leather steering wheel and DAB radio.

Along with adaptive cruise control, you get cab air conditioning, a heated windscreen, LED headlamps and alloys. My test model had an auto gearbox too.

I found the cab seats to be some of the easiest to swivel that I have come across, and the driver’s seat comes with a handy reading spotlight, too.

The clip-on table in the dinette just behind includes two drinks holders, so the two people sitting in the travel seats are well equipped en route.

Adria has clearly sought to make this lounge feel more upmarket than the standard Twins, with a warm wood tone to the lockers and the underside of the bench seat. There’s masses of daylight here, thanks to a huge Heki overhead, and you get three adjustable spotlights. Sockets for a TV are behind the bench seat, so the screen could be viewed by anyone in the cab seats.

The warm wood tone continues in the side kitchen, which is fitted with a two-burner gas hob and inline sink. There’s good workspace to the left of the hob, thanks to an extension that slides out like a drawer with a separate board you need to fit in. This is fiddly, but results in a very sturdy surface. There are hooks for tea towels behind the sink, and a socket, too, although you would probably have to put the sink cover in place to use it.

Adria’s designers have managed to fit an 84-litre slimline fridge in here, but just as I thought it was just as impressive to see the removable bag for spices in the overhead locker: you can take this out for a barbecue.

The washroom, which has a swinging partition, provides a shower on one side – slightly cramped but with good headroom – while on the other side, the salad-bowl-style basin by the toilet has a large mirror behind it. There are two towel hooks, a light and a vent, but only one drain hole in the shower.

The huge bed at the rear is lowered electronically and folds out a little on the sides once it is past the overhead lockers. This makes using a fitted base sheet an absolute doddle, while the single-panel bed is extra comfortable.

In the daytime, once you have fitted the bed neatly back into the roof, you then have a huge space for working on anything you might have brought with you, such as bicycles.

When the bed is lowered, you won’t be able to access the overhead lockers, but underneath, there are two handy workbenches that come with covers.

Elsewhere in the vehicle, you get two deep overhead lockers in the front lounge, sizeable drawers and lockers in the kitchen, and a small cupboard in the washroom.

The majority of these lockers rely on push catches to open.

Alternatives to consider

The Bailey Endeavour B62 is a well-specified ‘van but has a U-shaped lounge at the rear, instead of benches. Alternatively, there’s the Adria Twin Supreme 600SX – when we saw it in 2023, we thought it came with excellent facilities and would be ideal for outdoor enthusiasts.
