Since you can easily scavange most of these things you only need the hard to find stuff, and stuff that will help you scavange. So body armor and the ak to keep you alive. Axe to help get into places for supplies. Jeep to haul your shit. Drive down to dicks and load up on the rest.

Long term you need a spear and knife for weapons. A horse and cart for hauling shit. Dog for guard duty. And ways to get water and food.
