Action Mobil created the Desert Challenger, the company's largest home on eight wheels.

The company spent several years planning and building the eight-wheeled RV that was ultimately sent to Saudia Arabia, according to the maker.

The Austria-based company predicts that the Desert Challenger may be the largest home on wheels with off-road capabilities that has ever been built. In total, the overlander — which weighs around 33.1 tons — is 39.4 feet long, 9.8 feet wide, and 12.3 feet tall.

Like any overlander, the Action Mobil's build comes with a living space, kitchen, and bathroom. But unlike most RVs, the Desert Challenger is equipped with unique features, such as a walk-in refrigerator and multiple surveillance cameras. All of these amenities amounts to a $1.75 million overlanding Desert Challenger, according to The Drive.
