The Crew Cab is the most versatile pack you will find. It can carry any type load of any weight. I would pick the CC over any of the "traditional" pack by Mystery Ranch if you plan on hauling meat as a primary use.
People complain about the price and weight of the MR packs, and it is obvious to me they've never owned one or carried a load. I owned quite a few other pack and hauled some pretty good loads and I wish I would have started out with a MR. To compare a Eberlestock or Badlands to them is like comparing a Suburban to a KIA, and yes, I've owned both.
