The storm cases store perfectly down the center aisle of my mansion on wheels. When I stop for the night, I can still use/sleep in the trailer without unpacking it.

Living in such a small space makes organization a high priority. The cases are packed and loaded in reverse order of their use. That is, the orange one which contains jacks, jack stands, wheel chocks rope, extension cords, and other landing gear/set-up equipment, goes in the trailer last and 99% of the time comes out first.
