Brabus, the legendary custom vehicle brand, has just built a matte-black penthouse on wheels called the ‘Big Boy 1200’.
It’s so much more than what it says on the tin, though.
Decked out with 1,200cm of granite and a classy interior that wouldn’t look out of place in a palace, this Brabus creation is more behemoth than ‘big’.
The Big Boy 1200 is the ultimate RV motorhome.

Brabus is a master of the craft when it comes to creating huge, aggressive, yet still luxurious machines.
The Germany-based supercar and automotive tuning experts recently partnered with Supercar Blondie to reveal its most powerful creation ever – the $600k ‘Rocket 1000’.
Whether it’s monstrous cars, electrifying speedboats, or even stunning watches, the brand has perfected its art.
Now, it’s the ‘Big Boy 1200‘ RV that is attracting well-deserved attention, as the matte black beastly motorhome is much more than a spruced-up caravan.

First up, this is a motorhome equipped with a whopping 12.8-liter six-cylinder turbodiesel engine that propels this 26,000kg behemoth up to a maximum speed of 56mph, allowing any lucky driver to take luxury on the road.
The matte black design is a signature of Brabus, whose impeccable interior class is often overshadowed by a meaner exterior.
But once you’re inside, it’s giving Buckingham Palace and Four Seasons penthouse vibes.
The trailer boasts king-sized bedrooms, a modern induction hob kitchen with a sleek couch dining area (which can multi-function as bunk bed areas for extra guests), and bathrooms fit for a king or queen.

We’ve seen some impressive motorhomes over the years, like the multi-million dollar custom RV owned by Will Smith, but this is one of the most well-designed ones yet.
Still, it’s completely juxtaposed to the all-white alien-like Marchi Mobile ‘eleMMent’ which looks like something from a sci-fi series.
Brabus has obviously conquered cars, and – for the time being – has set its sights on the rest of the vehicular world.
The Big Boy 1200 is a statement to all luxury designers that there’s a new breakout competitor in the RV space – and they’d better try to keep up.
