I want to challenge you to carry all that stuff and walk for three days in any direction you choose. Camp out every night and get up and walk in the morning. I can guarantee that 3/4 of that stuff will end up on the ground before you get to your destination. Keep it lightweight, keep it simple and your kit, your feet and your back won't fail on you.
Needs are food, water, shelter and you can live three days without food. If you have to carry it, not carrying it in your truck, you will find ways to shed weight like despised in-laws.
Water is more plentiful on the East coast so its easier to walk long distances without worrying about dying of thirst. Desert walking, the majority of your pack weight will be water. You will walk at night as much as possible to stay out of the sun and to avoid using up your water and you will stay warmer moving at night. Following the 2 is 1, 1 is none principal, have two different ways to treat your water. I prefer a Sawyer filter, but Aqua Mira drops, or tablets, are a backup in my bag. I have a SAK classic in my FAK and a small folding Gerber handy in case I need to open a foil pack of tuna or carve a tent stake or a spoon. Two headlamps with Lithium batteries and spares batteries. I carry my cell phone and an Anker 10,000 battery bank to recharge it. If I keep my phone in airplane mode and shut it off when I'm sleeping, it will easily last a week.
Of course this is assuming civilization hasn't gone completely to shit and someone is still around to look for you.
