I used a freighter frame with what they call a "moose bag" for years for hunting & packing all kinds of stuff. Holds a lot of gear, and with all but the biggest moose the quarters would fit in whole (1 at a time !). If something doesn't fit in it I take the pins holding the bag out, remove the "bag", and strap things directly to the pack. But I bought a large internal frame 6 or 7 years ago and what a difference. A moose quarter will not fit in it, but pretty sure an elk quarter would, easily holds caribou quarters, depending on the size of the animal someimes 2 caribou quarters plus some other stuff. The internal frames are so much more comfortable and quieter. Mine is a Lowe Classic (I think), and got it for a little over 100 bucks. My 2 cents.
