Yes. Many of the higher/highest level Crossfit athletes/coaches have caught on to this and are adopting zone 2 building blocks. You still won't see it at your neighborhood Crossfit box because it doesn't fit the format, though.
You need to spend the majority of your training doing the thing you are training to do. For a hunter, this is hiking. At a minimum, you need to do it under your own body weight with a lot of your time spent on an incline. Because biking and rowing are seated, they are less than optimal. Better than nothing, but should only be a minimal part of your zone 2 conditioning.
Yes. Strength progression will be slower, perhaps much slower, even painfully slower at times, but it can be done. You have to temper your expectations when compared to aggressive strength programs. You can, however, get a jump on strength progression during the off season with the mindset that you may very well stall or get weaker once your conditioning volume increases to a certain point. The more training volume you add, the more you'll have to manage your strength training volume. This will become more critical at around 35 years old, again mid to late 40s and yet again around 55-60+ with potential significant adjustments for volume and recovery at each threshold. Genetics, training history, nutrition, recovery management will all play roles in this.
If you really want to compete in the Crossfit games, cool (That's so 2014, but you do you). If you want to excel at endurance, you should immediately suspend all Crossfit once the games are completed and dedicate your focus to endurance supported by strength training. Do that through hunting season and then switch back to Crossfit games prep for an offseason activity. Doing both will invariably end up being a disaster. Guaranteed.
