Do you think te 2300 is big enough to put meat in if I need?
I wouldn't be scared to haul meat with it. I have a MR Bighorn which is similar but a little bigger at 3000 ci and I've packed pieces of multiple animals with it. With the three zip its really easy to get pieces in to the main body of the pack, but you may not be able to zip the lid closed depending on the height of the load; not a big deal IMO. What I usually do is haul my first (or only depending on animal) with the bighorn and then have my bigger pack in the truck for the rest of the loads. Are you thinking fully boned or bone in quarters? I think there are a couple people on here that have packed animals with DS's.
Edit; I see Randy and I were having the same thoughts at the same time.
