CMO pretty well summed it up
"Your mind is your greatest asset. The ability to think when times are bad and to notice what others are doing. I'm not worried about the food being gone, I'm worried what other people will do once food is gone."
I have a plan and it doesn't include all that fancy expensive stuff.
Mine is old fashion "KISS".
plus there is one thing else,
I am an old man and I don't give a shit anymore.
Remember the saying about "never pick a fight with an old man"?
Anyway, the thing I always point to with such gear is, if you have all your preps laid out on the living room floor, which would be your highest priority to take if you have to leave on foot? Anything you carry will add to the weight and bulk, so thousands of rounds of ammo, 15 guns and all that body armor isn't going to be at the top of my list.
When you're spending your money, it makes more sense to get the higher priced things if they save on weight and bulkiness. Ever go hiking with a 50 lb backpack, up and down hills, in and out of heavily wooded areas with rocks, downed trees and holes that can twist an ankle every 20 feet or so? Ever go hunting with a rifle that weighs over 5 lbs?
Remember the opening scenes from the movie
Platoon where Elias (Willem Dafoe) went to each noob and told them what to leave behind before they went on patrol? You'll die of heatstroke trying to pack everything you "might" need.
Now, if you have a bug-out vehicle with room to carry stuff and are sure you'll never have to abandon it (no gas, flat tires, or mechanical failure), then load up! Just be aware that may make you a bigger target for the "have nots."
Learning to travel by air with just one carry-on suitcase was difficult for me to learn. Packing for a week meant at least one big checked bag. Now I can go for 1-2 weeks with a single carry-on suitcase. Of course, If I have a firearm, the bag can be larger since I have to check it anyway.
The thing is, I had to force myself to make do with what I'd brought. I'd leave behind most toiletries except for bare essentials should I be stuck overnight somewhere and buy what I needed wherever I was. The clothes I traveled in were chosen so I could wear them for casual outings. I'd pick two sets of clothes for my meetings, and enough clean underwear/T-shirts for 4 days. I could wash everything halfway into the trip and have clean clothes for a whole week. Undershirts help keep your shirts clean longer, too.
I can't tell you how nice it was to bypass baggage claim and be able to manage all my luggage easily as I went to rental car counters and hotel check-ins. Being able to carry everything in one trip rather than needing a car, cart or assistance makes traveling much nicer overall.
I try to apply that to my bug-out planning. Minimize, reduce, and prioritize. Think about water alone. That stuff is HEAVY! So, either you know where you can get more along the way, or you leave something else behind to carry water. Simple example.
