COLO western: I remember my first back pack Hunt in which I used (made do with?) a Trapper Nelson pack frame.
I have used Kelty stuff over the years and my favorite for a while (for Mt. Goat hunting at least) was a big bagged pack frame that also unfolded into a cot to sleep on!
Kept me up off of the wet on several trips.
