About all you really need in your situation for long term survival, is food storage.
You seem to have enough acreage and the location that you can deal somewhat easily with the issues that we city dwellers face, especially in desert areas.
I think so too. We have been gradually stockpiling various types of foods. We have some cases of the number 10 size cans that are good for at least 20 years, and plenty of regular canned, frozen, or dehydrated stuff, first aid, etc.
And of course we have planted fruit, nut trees, and berry bushes as well as a regular garden, which we could expand and store even more than we do now.
The rural area has it’s advantages - we have a creek, well, swimming pool holding 4000 gallons and a septic tank. The well can be run on generator(it’s a pain to hook up) or use a narrow bucket.
When the electricity goes off, we immediately draw water from the lines by collecting it in gallon jugs or empty soda bottles.
We also keep about 20 gallons of bottled water on hand, but have never had to use it. The lines always give us enough water to get through so far - but we are prepared for longer term pretty well, I think.
We do a little more every chance we get.
