"As a half-dozen or so Applied employees watch, Ferren steps off a ladder, slides into the truck’s cab, and begins fussing with a black leather chair that’s been mounted in the back of the truck’s cab for Kira to ride in. One of Ferren’s primary concerns when designing the backseat was making sure his daughter wouldn’t endure an unpleasantly bumpy ride."
"Ferren leaves the chair for now and gives me a tour of the vehicle, starting with the front cab. Like his MaxiMog, the KiraVan is adapted from a Mercedes-Benz Unimog. Ferren and his team have gutted most of the original equipment, leaving only the steering wheel and a few smaller components. Among their numerous additions are a series of custom-made, overhead- and dash-mounted touchscreen cockpit displays, which monitor the vehicle’s health and navigational progress; a joystick-operated situational-awareness system, which allows passengers to see the view from any one of the vehicles’ 22 cameras and provides infrared thermal imagery of the road’s temperature; and an emergency-beacon locator-transmitter, which goes off automatically in case of an accident—if, say, the vehicle flips over."
"We step out of the cab and examine the chassis. He’d originally wanted to import a newer, extra-strength chassis from Europe, but when that proved to be a bureaucratic nightmare he decided to modify the existing model, which he lengthened and doubled for more reinforcement—a process that took months."
"We move on to the trailer, which at the moment sits toward the back of the garage. Walking through a swing-out door, I find myself in a bathroom with a sink, shower area, and retractable toilet"
"Much of the trailer is still under construction, but there’s already a wall of kitchen equipment, including a convection oven, a microwave, and an induction-cooktop stove."
So it is 100% real but that is not to say the images you looked at were not manipulated in some way
