@Maverick1 what is your deer setup?
Which one? LOL. I have three different setups!
For saddle hunting, I use an Eberlestock X2 pack.
For treestand hunting, I use a Red Rock Diplomat pack
For hybrid, I use a Condor 3 day assault pack equivalent (essentially the same as the Red Rock Diplomat.)
The above backpacks are for carrying in gear (sticks, platforms, stands, clothing, food, water, etc.). If I shoot a deer, I quarter it and backpack it out using a Kelty Cache hauler.
I've tried a number of packs over the years, with a variety of sticks and platforms/stands. Some were better than others. The above is what I have used for the last couple of years.
The X2 works well - I'd like the frame to be a little bit taller to get more lift, but the saddle setup does not weigh very much, meaning the load lifter angle really isn't a big deal, so I've kept that setup as-is for the last couple of years. I would not use the X2 for hauling any kind of significant weight, ever.
The Red Rock Diplomat/Condor 3-day Assault packs are spacious, with plenty of pockets - if anything they are a bit too big and heavier than they need to be for how I use them. Their frame sheet is juvenile and load lifters are non-existent, but they way I use them those things are irrelevant.
Depending on which stand and sticks I'm using, I can either
1.) attach the sticks to the side of the backpack and then attach the backpack/sticks combo to the stand, (Beast sticks/LWCG sticks; and Beast stand) or
2.) attach the sticks to the stand and then attach the backpack to the stand by itself. (LWCG double step sticks/LWCG compacts; and either LWCG .5/.75 stands)
Edit to add more information:
The Red Rock Diplomat, Condor 3 day assault, and "World Famous Sports" large 3 day tactical backpacks are all essentially the same thing.
