My set up is a Kelty Load hauler frame with two MR load cells on the shelf and a 40 liter day pack on top of that, with any large or bulky stuff lashed on, (sleeping pad, tent, etc.). Its a set up I've been looking for for years. Just drop the frame and grab the day pack and go. No digging through gear looking for the stuff I want in my day pack and no forgeting stuff. Might not be the lightest or best setup but it works for me.
