Much is going to depend on what’s happened.
Around here, if SHTF is a major blizzard, you ain’t going anywhere without a sled (snow machine) or a horse. It is that simple.
EMP? There are a lot of older vehicles, but how far will they make it.
For all realistic BO situations, we’re taking two vehicles.
The Suburban and my Bronco.
We can carry enough food and supplies as well as the kids and dogs.
Tents, sleeping bags, the normal camping gear. (Around here, winter gear is year round for most areas)
Pioneer tools (axe, shovels, adz, pick/mattox, chainsaw and accessories, hardware, etc)
Fire grate, chuckwagon box
