Winter Housing For a single father and child

We've been here a year and have been working one way or the other for almost the entire time. Like most, it's always been paycheck to paycheck. I've recently been fired, without cause and been displaced, we do have a place we can camp and also build our dream home in the form of a bus. There are several options available but one is right down the road for cheap! Please help if possible, even sharing will help us get closer to our goal. Peace and love.
