While I'm not a doc yet, I shadowed an ortho doc all summer... A simple way to tell which ligament is torn is to see which way your knee is unstable. If your tibia slides forward compared to your femur, your ACL is torn. If your tibia slides backwards, your PCL is torn. The reconstructive surgery is a big one. Like 4-6 months until the new ligament heals into the holes they drill into your bones. Anyways, if the instability and pain aren't that bothersome, you'll actually probably be able to avoid surgery until after your hunt and simply get by with some sort of brace that will restrict some knee movement. FYI: There are people that go about their daily lives with completely torn ACL's (and I think PCL's even more so), but it doesn't bother them unless they perform twisting or cutting motions (which a surprising number of people don't do on a regular basis). For instance, you can get by running a 5K with a torn ACL because it's just straight ahead motion, but you wouldn't be able to play basketball or soccer or maybe even swing a golf club because of the twisting and cutting. Just be careful so you don't end up stranded on a mountain somewhere.
