if you can live with a bit of bulk the Alpz Commander frame is a good deal.
I bought the full setup with the (80l?) bolt on pack included, but 90% of the time I leave the big bag at home and just strap a small 35l pack to the frame for stuff that needs to be bagged, and anything else (tent, bedroll etc) just gets strapped directly to the frame. Once you get to basecamp off/out comes all the unnecessary gear and your left with just the (now)daypack and meat carrying system ready to go.
Full disclosure, the width/height of it can be pretty cumbersome in real thick stuff (bearing in mind the top rail is detatchable, which helps slim it down some and it doesnt seem to flex at all with it off), but you can load the thing up with more dead stuff than any human could carry and the whole load stays stable. Way better than having multiple meat bags or haunches or whatever swinging every which way while you're hiking out. has a a rifle holder too.
