Hey there Rob!
I can relate. I have the same frame and did just what you are planning for the past two years. Will be lucky enough to do it again on the PBS elk hunt in a few weeks.
My Alaskan frame is the original Camp Trails before Cabelas claimed it and I am using the Eberlestock X2 daypack. I put my 3 day spike camp, kitchen, food and a few extra pieces of clothing into a drybag (12.5 pounds) and arranged it to distribute the weight evenly and lay stable across the fold out shelf of the frame. A few lightweight buckle straps to lash it in place. I set my daypack, fully loaded (26 pounds) and ready to hunt on top of the camp bag with the outside(back) of the daypack to the Alaskan frame. This put the shoulder straps and waistbelt out where I could cinch them down, tuck them in or even wrap them around more cargo if I wanted. A pair of buckle straps to lash it to the frame and I was ready to go. This was less than 40 pounds on the frame and carried pretty easy. No problems with a side quiver over my shoulder, binos on a neck strap and bow in hand. I also left my H2O bladder in its normal daypack pocket but fed the tube forward and clipped it to my pack frame shoulder strap for use while hiking.
This seemed a good solution for spiking away from base camp but having a freighter frame to ferry big meat loads without having to go all the way back to base to get it. I was hunting up to 3 miles from spike camp and that was 7 miles from base camp. I suppose an upgrade in pack would be nice but I had these two packs and not much budget and it has worked out without problems so far. I may not be the most stylish guy on the mountain but I was hunting elk!
Good luck in CO! Enjoy the whole trip and bring back pics. Shoot straight when you get the chance.
