My opinion....I survived the collapse of USSR and all that followed: cartels taking power, unrest, riots, total lack of food, overall mayhem, in all spheres of life, etc, there were wars all over the periphery. People here discuss expensive crap, tons of tech gadgets, radios, generators, rockets to fly to the Moon, years worth of GMO food crap, etc, etc. Most of what's written here shows people have no clue of what it's like to live through societal collapse.
One thing: guns won't help you...not for a long time. You might shoot a robber or two, but there'll be organized criminals, with guns, outnumbering you and much better organized. They'll kill you just for your guns , ammo, gold, and for your tech survival toys. May be even for your crops, if you try to protect them. The less you have/own, the safer you are. They'll find where your gold and guns are, by torturing you, if they think you got something worth taking, and the word spreads fast... It could be your nice neighbors, who'd tip someone off. Another thing: your nice neighbors you think you can rely upon very likely won't open the door for you.
Live low key, don't focus on material possessions. Urban real estate is the best hedge against this stuff usually (except if it comes to bombing), as all collapses eventually end and things come back up, urban areas tend to do much better in those. Rural RE: not so much....it might end up being worth only the potatoes and goats you can grow around that house, which will be very likely to end up being burned down. Not much incentive to go after an old RV...but much to rob and burn the house built to complete with the Johnses, they won't have enough "guards" for those.
Relax and enjoy your life. You won't face STHF during your lifetime, by all chances. The worst SHTF happening here will probably be Happy in Wyoming having a legal dispute with neighbors over parking of his armored RV
