I have the CC and 6500 as well. I use my CC for Day trips where I will hauling meat and my 6500 for over nights. You could get away with the CC for a short 2 or 3 day trip but its going to be tight if your hauling out meat.
The dry bag method works but I prefer to have my stuff some what organized. The CC excels as a meat hauler that you can store some gear in.
If your looking for a extended stay pack go with the nice 6500 over the CC.
Also keep in mind load lifters are not made to lift the load onto your sholders. They are two bring the load closer to your body. Let the hip belt carry the loads.
