My stock boxes are 37 and 45 liters, offset for the exhaust. I can get all my tools, kitchen (fire prep/stoves/food and prep), house (hammock setup), clothing and other gear (including a small table and chair) into those boxes with optional fishing gear, a kite to fly and my toiletries in the lid mesh netting. My soft bags are 25L each and I can run a 30L or 40L tail bag if needed. I'm enjoying playing with the weight and balance of the gear and seeing how much I need and how small I can pack it all. Sometimes if I can't sleep at night I just unpack, sort through and repack to see if I can do it better. I'm loving how backpacking translates to this process.
