Greywolf, we must think alike. I had in mind most them details. I have had a safe house on mind for a lil while now to store gear and whatever. The main thing which you said that got my attention was Solar power, i had a few panels for my design. I thought that would be a great idea, its a silent form to produce electricity and lil/no maintenance, generators produce to much noise/exhaust to be heard or smelled.
