Do you have a tire size in mind? Pick one and then it gets built around them.
Your current axles are good to 35" tires with the right parts.after 35's
you need d60s(because of ball joints of all things)Dana 44 front doesn't add much strength. 35's and larger are very expensive to build a reliable(and safe) rig around though so keep that in mind.
For your 32's I'd get 4cyl 4.10 axles and run arb or elockers with an s35 kit.they will be cheaper than regearing.
For hunting by myself way out there I'd want lockers,lots of synthetic not steel recovery gear.survival supplies for an extended stay,navigation gear both paper and gps,and coms that will reach out. Make sure you have the oem tire changing equipment.
How do you plan to bring the elk back? Inside?on top? I love a cordless sawzall with pruning blades for quartering large animals. Works great on bone. I've done a few cows easily with one. But i wouldn't pack one all over,lol!
