One problem for me is space. I don't have a basement like in a regular house, and the attic is too hot or too cold. So, I have Rubbermaid containers stacked as best as I can. Since my daughter moved out, her old room has become storage area, so that helps, at least until she moves back!

Another issue is my truck. I have the far end unit in a row of townhouses, so it's parked about 50 yards away. That makes it tough to move things back and forth, and I also don't feel comfortable leaving valuable items in it, even though I have a big locking truck-bed tool box. Although bugging out is a last resort for me, it would be a chore getting a lot of gear ready to move.
