I dismantle the F2: I removed a small screw (the one that stops the shift from going too far) on each carrier frames so I can remove the frames (shift the frames out).
I pack the two standards in a small soft fabric coolbox (to carry lunch, sandwish). The frames and the back with gg are wrapped in the dark cloth.
It reduce volume significantly and I feel it is better protected than leaving it half mounted in the bag.
I use a standard front load hiking backpack bought (redwing something bought us$80 at REI). The lenses, spot meter, extra bellows, compendium, loupe, filters, gaffer tape, leatherman, stopwatch, gps all in small fabric coolbox bought again at REI. intermediate bellow holder, sinar tilt head and rail fit on their own without any wrapping.
I use a stop watch now. Before I used my cell phone to time the shots, but the phone fell out of my pocket into the sea when I was in Illulisat (in Greenland). Better to break a cheap stop watch than phone when traveling in remote places.
For the sinar p, I also de-couple the frame from the holder (the back one). For the front frame, I need a screw driver which is not convenient in the field (I just leave it as is wrapped in the cloth), so I am thinking of using two back standards. The 8x10 back goes in a large fabric coolbox along with the holders. The holders are placed in a rigid and light plastic satchel.
I found the trick of folding the frames onto the rail makes the camera too bulky and does not fit easily in the bag with all the rest of the equipment. I have to take the camera apart every time. I usually walk around, found a spot, settle and gently (with love and care) mount the camera. It goes fast when used to it. It's all about the process, right?
