Also, thanks for this. I messed around with it a bit and it got a lot simpler.@woods89 changing the frame extensions should only require loosening the shoulder straps and load lifter straps, then loosening or undoing the three straps of the panel that wrap the bottom of the frame.
Then slide the panel up, being careful not to lose the little caps that cover the frame/extensions, and slip the extensions in/out. It might take 5min total.
I don't adjust the torso length.
