If I understand correctly, the "base camp" concept discussed in this thread is just what I think of as a "survival retreat" by another name.

The dfferences are that the base camp:

(1) uses camping out gear as opposed to a home, cave, or more traditional, durable dwelling choice, and

(2) as discussed in this thread seems to assume the base camp will be set up within the 72 hour, plus or minus, walking range for which I understand a BOB is usually designed.

If my understanding is correct, then I would suggest you should consider pre-selecting your base camp spot and locating a survival stash there with the heavier stuff. Then you are back to using your EDC and a lighter BOB to get there.
