The new Brabus Big Boy 1200 motorhome is essentially a mansion on wheels

This is the new Brabus Big Boy 1200, a massive luxury motorhome that cost more than a supercar.

It’s 40 feet long and over 12 feet tall.

Entirely lined in genuine granite, it reportedly comes with a seven-figure price tag.

But once you look inside, it’ll be easy to understand why.

A closer look at the 40-foot Brabus Big Boy 1200 luxury motorhome

The interior looks like it belongs to a five-star hotel.

It boasts a duo of extendable slide-outs transforming the bedroom and living space to a space nearing 15 feet in width.

You’ve got leather upholstery, mixed with wood and carbon, and granite for the shower.

The Brabus RV is also bedecked with high-end digital and entertainment tech, along with streaming and browsing connection courtesy of SpaceX’s Starlink.

Did we mention the 4K television and PlayStation 5 system?

Maybe Simon Cowell could consider this once he decides to replace his $2.1 million double-decker luxury motorhome that’s like a mansion on wheels.

Or maybe Justin Bieber could do the same with his tour bus.

An equally massive engine under the hood

The name Big Boy 1200 is a reference to its size, but also its engine.

For once, 1200 isn’t the amount of horsepower, but it is – in part – a reference to the engine size.

Under the hood of this gigantic RV you’ll find an equally enormous engine.

It’s a 12.8-liter, six-cylinder turbodiesel unit capable of putting out 530 horsepower with a maximum torque of 2,600Nm.

The result is a top speed is limited to 56mph made comfortable with a three-axle chassis and twin rear tires.

To be fair, we reckon the would-be buyer of this beast won’t care too much about top speed anyway.
