Respectfully disagree, Seraph... Your idea to have it all abstract into a single bland tally of a generic ''camp supply' resource is the exact opposite of maintaining the flavour of the concept - it abolishes said flavour entirely. I dislike and do not support that idea.
Sure, it would be better for immersion if you have to carry the items with you, and they only automatically dropped into the isolated 'supply stash' when you actually went to camp; YES, that would be better for immersion ,and the consideration of weight limits... HOWEVER, we already have a free, always available "send to camp" button that you can use on anything, at any time... so there is NO point in implementing anything that preserves realism of having to carry camping materials until that is taken away - and it doesn't look like it will be. EVEN then, We ALSO have an automatic and free any-time-any-where travel to camp button that lets us pop to camp and back to where we left again at any time... and that would have to go too.
Are those things going to go away? Most likely not. If those things don't go away, then any system that is making you carry around a weight of materials that are only used in your camp is going to simply be stupid, inefficient, and will not preserve immersion at all, since everyone will simply circumvent it using the game's own in-built mechanics for doing so.
