I take a layered approach. I have to carry a work laptop back and forth to work each day and have a backpack given by work with the laptop. I made up a small edc bag which contains some minimal gear. Then a small pack under the seat of my truck for a GHB then a backpack at home that fits best in the BOB category with hiking/biking/outdoor gear. Next layer is more of an urban BOB since we would most likely bug out to a hotel so the urban bob is a suitcase with as much pre-packed as possible. After that are the document binder and contents of the gun safe, camper, various tool and gear bags, etc.
