Something to consider when building your mobile living space. That is the length, width and height of anything you are considering living in. Square footage is relative, we may both have a 10 x 6 x 6 space normally considered 60 sq. ft. It is actually 360 cubic feet. The more you put in that space the less living space you have although the dimensions don't change. I may have much more living space than you because I choose to keep to a minimum what I build in or carry onboard.
