Unsettling, going nomadic, is trending like an idler pulley on a high single pivot. Perhaps the attraction is that the alternative is to settle, which sounds like an uninspiring, underwhelming compromise.
Everything happens in cycles. In the 1930s, motor bungalows and rolling homes were popularized as cheap portable living spaces for the poor and as vacation wagons for the more fortunate. A nice new Schult trailer could be had for just $275 in 1934. Returning from war and through the Great Depression, many had trouble finding housing and jobs. By necessity, people were living on the move, trying to find a place with some work, or just a place to disappear and get by with as little as possible.
With fallout from the financial crises of 2008, people again turned to the home on wheels as a more affordable way to live, escape, or means to move from place to place where intermittent employment might be found. The current surge in nomad life is further fueled by images of cozy wood clad van interiors, draped patio lights, a steaming cup of coffee, and doors opened to panoramic views.
