A hatchback or small SUV with the seats folded down is adequate for that. I fit a full size refrigerator and a 3 seat sofa in my scion xB (no not at the same time).
Got a prius now and fit two IKEA mattresses and bedframes no problem.
Plus you don't need to worry about people just deciding to grab shit since it's enclosed.
Double gas price not enough motivation to go more fuel efficient? It's economics.
I hope they like insurance claims
Fun fact: In communist China (present day) there are entire cities built and left empty to meet top-down government mandates.
Official sanitized reports show 2~2.5 million homeless Chinese, while up to 300 million suffer from housing insecurity. That's a homeless population that is nearly the population of the entire USA.
Not only that, but in this example of communism you need a permit to move to a city so you can be an illegal immigrant in your own country.
