According to the Korean automaker's patent application, the camping market is growing, and it believes this idea would appeal to customers. "Camping has evolved from a level of just sleeping outdoors to include a step of taking a rest outdoors, and therefore, camping equipment has also continuously evolved," Hyundai states in the application.
In addition to the novel door design, it's interesting that Hyundai specifically imagines this on an RV. In the UK, a company converts Hyundai's i800 van into a camper. Perhaps the Korean automaker sees space to do something new in the segment with this patent. We hope the company shows a vehicle in North America with this door because we want to see the contraption at work in the real world.
