Another way to look at it is as a GET HOME BAG (GHB.)
If you travel a lot and have to get home, what will that take?
What is the distance?
How long would it take for you to get home?
How long would it take walking?
Do you work in the same direction(s) all the time to allow for caches?

If you think of it this way and prioritize what you need to “get home” your ‘BOB’ will shrink conciderably!

In order to truly bugout, a 6-ton truck would be most appropriate going to a prepared location, imo!
