We sold all of our stuff, moved out of our 5000 sq ft "McMansion" near DC and spent a year wandering the country exploring "the spaces in-between". We lived in a trailer that I could pull behind my pickup and all of our possessions fit in the back of said pickup.

It was intensely liberating. Sadly as soon as we settled down again, the stuff started acreting like barnacles. Our plan is to repeat the process on a semi-regular basis.
