Once stationary, four power-assisted modules extend out of the body to increase the scale of both the bedroom and ‘saloon’, providing a massive 30 square metres of living space. That’s around the same as a small one-bed flat in London.
Hydraulically extendable supports also level the vehicle perfectly on any surface while entry and exit is provided by electrically retracting steps on the right-hand side.
Security is provided by a 360-degree camera surveillance system with a direct feed into the living room and a four-digit entry code is required to unlock the doors.
Make your way into the ‘masterpiece living space’ and you’ll find a bedroom, kitchen, shower room, dining area and lounge.
All the floors are heated throughout and there’s a night heater and automatic air conditioning to guarantee stable temperatures no matter where you’re driving to. Both are powered by eight solar panels on the roof and the Big Boy’s on-board energy storage system.
The bedroom compartment, courtesy of the two extendable modules, provides enough space for a transversely positioned double bed. There’s a single bed that electrically lowers into the vehicle cockpit for additional sleeping space if required.
There’s a large closet integrated into the rear wall of the motorhome’s bedroom, while there’s a desk and a 43-inch 4K television installed in the side wall opposite the bed with a Playstation 5 for gamers.
‘Thanks to satellite internet via Starlink, passengers can watch streaming services, access content from the internet or communicate with the whole world, even in remote areas,’ Brabus boasts.
Moving into the living room, there’s two grey leather sofas that – like the driver and front passenger seat – are ‘quilted with pinpoint precision’ and face a second 43-inch telly.
To further bolster the comforts in addition to the underfloor heating, the living areas has Sahari luxury carpets, while other sections are finished in black fine wood or in matching black Alcantara.
The saloon features a modern kitchen with an induction hob, oven, dishwasher and fridge with an integrated freezer compartment.
A separate wine fridge and coffee machine are installed for all your beverage needs.
The sofa opposite the kitchen, together with designer chairs and a large black table, provide an interior dining space that will easily accommodate four people.
Finally, there’s a lavish bathroom featuring natural stone walls, a rainforest shower, and matching black WC and heated towel rail. A separate – though stunning – vanity area leads into the sleeping quarters.
From the outside, the enormous dimensions of the Big Boy 1200 are elevated by an all-black exterior giving this not-so-subtle machine a stealth-like look – though definitely not stealth-like characteristics.
It even comes equipped with a roof light bar, just in case your desired destination takes you off-piste and well away from streetlamps.
Want one? Well, Brabus says it retails for a starting price of €1,260,504. Today, this converts to just over £1million (£1,057,000), so quite a lot more than a weekend at a Haven resort.
