Press a button in what looks like a fairly conventional motorhome and the foremost roof section over the cab rises. It only takes 90 seconds to raise the overcab with the aid of compressed air and a specially developed chamber system – this is a whole lot more sophisticated than a conventional pop-top! When elevated, the vehicle becomes 3.70m high, but Bürstner has thoroughly tested its Gallery roof – in temperatures from minus 30 to plus 80 degrees Celsius, as well as with snow 1.5m deep and in winds of up to 120km/h.

Inside reveals a spacious overcab bedroom, accessed by a true staircase that’s even illuminated, as well as incorporating additional storage.

Roof aside, the Gallery adopts the high spec of other Harmony Line models with a contemporary exterior and diamond quilted upholstery inside. Of course, it has Bürstner’s Thermo-Floor, too, to ensure all-season comfort on board.

The 689 G is one of two models in the range, both of which are under 7m in length. Here, the layout features an L-shaped settee up front along with twin swivel cab seats. The central kitchen, backing onto the lounge, is also L-shaped, with a tall, 142-litre fridge opposite. Then, across the rear, is a full-width washroom with separate shower and giant wardrobe, under which is the garage.
