Edited to add: I lived with my two small dogs in a 22 foot travel trailer for about a year, if you don't have a lot of "stuff" it's not too bad for one person.. For an adult with four kids and a couple of pets it's most likely hellish, although less hellish than living in car on the street would be.
http://www.salon.com/life/pinched/2010/04/12/five_kids_in_a_trailer/index.htmlTwo years ago my children and I were living in a nice five-bedroom house in Colorado, and the decline of the housing market was just an abstract worry. I had plopped down almost all of my life's savings (including cashed-out retirement funds) on the down payment for our house to keep monthly payments low. I was employed in the environmental-permitting field and able to pay the mortgage. My worry was more personal: My young son was not growing. Adopted at age 3 with a successfully repaired heart defect, he had weighed 28 pounds for the nearly two years we had lived in Colorado. After what seemed like endless tests and failed fixes, we learned his lungs had suffered permanent damage in the 18 months before his heart was repaired.
"If he were my son," the doctor said, "I'd move to a lower elevation."
I landed a new job in California quickly -- so quickly, in fact, that we didn't have time to sell the house, an already difficult prospect in a down market. At the last minute, I agreed to rent it to a neighbor's friend who'd hit his own hard times -- his wife had left him. He was a contractor, and since the home needed minor repairs before we listed it, this seemed like a "win-win." Instead, it was a disaster: He never paid a dime, offering six months of excuses that came to an end, eventually, with a court order allowing the sheriff to remove him. But by then, the bank was waiting to take possession; my salary couldn't cover rent in California and our mortgage in Colorado. In March 2009, we lost our house.
The job followed about six months later, a victim of "overhead reduction" layoffs. And with no income, or assets, our landlord asked us to leave our rented house. We sold nearly everything we owned and prepared to move again -- this time into tents.Read the rest of the article at the link..
