I mostly want it for a back up for power outages, and perhaps the big
one when all America goes without power after the solar flare.
Need backup food and water for at least 2-3 months. Some gas and
kerosene. Maybe a gun.
Also cb and ham communications, the only things available.

Good plan. Regarding the gun: get two. A long gun and a pistol.

Also hoard a vast quantity of ammunition, at least a thousand rounds for
each.

In a complete breakdown of society, ammunition is the new gold.

With sufficient bullets, all other things are obtainable.
