I agree that archery is a grind because there are so many daylight hours. Regardless of your choice to truck or spike camp look for places that inhibit other hunters like river crossings, walking around the private land boundary, or steep grade that flattens out. The elk will be where they feel safe so look for those places. If you hike a trail 5 miles in from a trailhead you will be surprised at how many hunters thought they could get away from the crowds with distance but the trail was an invite, not a barrier.
You need to be willing to hike back to your camp in the dark because the first and last 30 minutes of the day is golden. Also, you need to be prepared to get the meat out. Solo backpacking in 5 miles is a challenge when you get a bull down and it is hot. Look on YouTube for elk hunting videos where people get bulls down and how they keep them cool while they are packing out quarters. I think Elk101 has some.
BackPack - You need a pack you can use to haul you spike camp in, hunt in, and haul elk out with. Do your research and look for used packs here on Rokslide or eBay. Look for guys that want the new models and want to dump their old ones. Besides selecting a bow setup this is probably the next hardest thing to buy but it can have a tremendous effect on your hunt. You will also need a way to filter water. Get a Sawyer MINI Water Filtration System.
learn to use a diaphragm elk call. If you are away from the crowds you can use calls to improve your odds and help stop the bull when they get close. Lots of YouTube videos on this. Watch the Born and Raised Outdoors Land of the Free series. Soft bugles and cow calls when there are lots of hunters around.
Get onX or BaseMap mapping software for your phone and a way to charge your phone if you stay multiple nights away from the truck. This is a game-changer. Use it to plan out where you want to go and find your way back.
Lastly get in shape. This is hard for everyone but it pays big.
Enjoy yourself. There is some beautiful country out here. Take some time to enjoy it.
