ummm no it is the same size as your XXL dry bag + 4000 cubic inches, so 2150 more. you can still use the drybag and meat shelf.
My point was I’d use the 4000 when I didn’t want to run the dry bag, so I’d still have to pack my gear extremely carefully. Thus it adds no versatility. There is also a practical limit as to how large of a pack you can have heavily loaded and then move it away from the frame by stuffing a full dry bag in there.
