I agree with the sentiment above. Organize into categories that make sense to you so you're not yard sailing the truck all the time. I did an archery whitetail hunt and rifle mule deer hunt last year and separated based on treestand vs spot and stalk. I'm guessing those are all elk hunts though, so the gear should be the same outside weapons. I'd probably be organized something like this. 
* Hotel/overnight backpack
* Pack and day 1 hunting gear
* Clothes
* Dry Food/Resupply
* Tools / Recovery
* Camp Cooking
* Weapons
* Coolers (guessing you'll need a lot but I'd put dry food, clothes, and maybe weapons in some of them to have less items to pull in and out) 
Basically get everything for each activity busted out then load based on need for access/weight distribution. I'd also look at a small chest freezer to get the meat frozen if it'll be riding around with you for the duration.
