Generators are nice but you can quickly run out of gas and that may not be available either. Everybody we know is coming to our house in the event of a catastrophy, they have told us put in more RV hookups as if they could drive their RV's out of the cities?
But we live near I5 and mauraders may be able to find us. We will need our friends and family to come and help protect the property. Saying this a little in jest, but I really would feel insecure living in a very big city with no escape plans.
Hate to say it, but it sounds like you are too close to population centers. If you want to be truly safe, you need to get far enough away to be out of range of any ground vehicles. That is, too far to reach on a tank of gas in a 4X4 or off road motorcycle and too far to walk in and return in a day from the nearest road that an RV can negotiate.
In a pinch you can make a wood burning heat/cook stove out of an old steel drum and a few feet of stove pipe. All you need is a hammer, a cold chisel and a punch or hand drill. I made one such for my friend’s cabin near Klamath Falls and spent all of 1973 and into ‘74 living there completely off the grid.
Anyone depending on an RV for survival is, in my opinion, deluding themselves. RV hookups? That’s a laugh.
Anyone who thinks they will defend their rural “Compound”, let alone suburban home, against marauding bands of opportunists should consider that anyone out foraging in force will likely be well organized and heavily armed. The best strategy will be to get so far away that you are not worth the trouble. Once you are found you will be the subject of repeated attacks.
Just my opinion. Worth no more or no less than any other.
