Bags are good for some things, not so good for others. Some parts of my truck kit are in hard plastic crates, my winter supplement (extra wool clothes and stuff) is in a couple large nylon duffel bags.

Any EDC items would be in addition to what is in the truck. The idea being that if I can get to the truck nekkid and hungry, I have everything I need.
