A GHB and 72 HR BOB are basically the same thing. If you get trapped away from home or have to leave home quickly for a short period... it should contain the items you would need to stay alive and hopefully stay comfortable. If you keep that in mind.... It's one bag. You can supplement it with a vehicle based bag that contains extra gear. I live in Colorado and change out gear based on the time of year. We are a high desert so it's very dry year round. It even gets chilly on summer evenings. So, I keep certain items year round.
A long term BOB is an entirely different matter and should be a two stage system as well. Your absolute essentials fit in the bag (in case you have to hoof it) and your "nice to haves" fit in a bag you'll carry for as long as you have a vehicle.
Hope that helps.
