As globalization expert Parag Khanna wrote in his new book, MOVE, the trailer home "is the ultimate symbol of the new American mobility." He told Insider that this type of small home is bigger than ever during the pandemic, and it's thanks to younger generations. Khanna's book explores how the youth are shaping the future with a mobile lifestyle. The trailer home is a key part of that, he wrote, emerging as a "trendy, cost-effective, and sustainable alternative to traditional homeownership."
