The 12m-long extravaganza designed by Austrian company Marchi Mobile features an ensuite master bedroom, pop-up roof terrace, underfloor heating and a bar.

Aside from its impressive master bedroom (did we mention there's a 102 centimetre flatscreen TV inside?), the vehicle also boasts a rainfall shower, separate toilet, lounge and driver's cab complete with bunk bed.











Mobile internet, a working fireplace, streaming video surveillance and satellite TV can also be fitted.

And, of course, there's the glow-in-the-dark paint.



So you could fork out for this mega motorhome... or splurge on this Double Bay mansion instead, which goes for about the same price.



It doesn't glow in the dark though.
