Like a lot of big names, when you want the best luxury RV in the business, you need to turn to Anderson Mobile Estates.

Anderson has provided motorhomes for countless celebs, including Simon Cowell, Will Smith, Vin Diesel, Jamie Foxx, and Sylvester Stallone. Oh and Bill Clinton.

But each is completely unique, with Mariah’s having been bespoke-made for her tastes.

The motorhome has 22 wheels, weighs in at around 40 tonnes and over its two levels offers some 1,200 square feet of space.

In fact, the main lounge has a 25-foot long slide-out section one side and a 30-foot one on the other side leaving 600 square feet of space in this room alone.

In the lounge is a 15-foot long sofa that was custom made with a wave design costing around £6,000.

On the tech front, there’s a 65-inch TV with surround sound audio to enjoy from the custom couch.

Next to the lounge is a very important room for Mariah’s performances – the make-up room. It’s fully kitted out with the finest cabinetry, mirrors and lighting.

At the rear is a double-height kitchen with fine wood finishes a full-size fridge, proper oven and hob and a £3,000 water purifier. Because why not.

But upstairs is where the biggest surprise comes – a full-size nightclub with a top-end sound system, 35-foot sofa to seat 30 people, ambient lighting and dual 60-inch TVs.

The TVs mean that when you’re done partying in the club, the upstairs can be switched to a Cinema.

This motorhome is so big it has to be towed by a full-size truck and Mariah uses it when she’s touring across America.

In total, it reportedly cost around £2million to build.4The upstairs converts from a cinema to a nightclubCredit: ANDERSONMOBILEESTATES4The lounge has a custom sofa and 65-inch TVCredit: ANDERSONMOBILEESTATES4There’s a full-size kitchen with £3,000 water purifierCredit: ANDERSONMOBILEESTATES
