When I lived in Coachella Valley there was one fellow with such a rig. He had created a large home-built trailer that he towed behind his bicycle. I saw him all over the valley and it was obvious that he lived in it. He kept to himself so I never got to speak to him or see inside it. So I can't tell you much more about it. The valley floor of the Coachella Valley was very flat, and I would see him pedaling along slowly with very very low gears.
