Hi and let me greet you with my most sincere welcome !
We share much in common. I have an Industrial Design background and in school days we kicked around
possibilities for micro homes for the Homeless. I had noticed the extensive use they make of grocery shopping carts and wanted to develop something along that line for them. Having been a Boy Scout in my youth I had plenty of experience with improvised outdoor living and shelter creation.
Here is the kind of things we came up with.

But wouldn't you know it. Some of the "Civic Leader Types" rejected this whole notion referring to them as
"Bum Boxes". They didn't even want to see a prototype exhibited. (the last two illustrations in the photo gallery are typical of what we came up with. Just drawings. I was wanting to work on something "geodesic"
that could expand from a box structure to create a small "zome" like the tiny homes that are popular today.
No doubt you've seen these expanding canopies that collapse to a very small bundle. This is an example
of an expansion structure that would be contained to use as part of the box.
As for your quest for experience in this realm, we have had difficult times before in the USA and
a Film industry with talented people to showcase life in those times. Fortunately they had a sense
of humor to go with it. You may find a kindred spirit in this Movie. And even more in the CRVL community.
