I just love it when people say never hunt too far form a road or ATV trail because you'll hate packing a moose or elk out of there. That's exactly why I hunt far from roads and trails. Gets rid of all the lazy hunting competition!
I consider a few items indispensable for hunting in the deep bush: A pack frame with large single compartment removable bag, some cotton meat sacks ( I use flour bags, or sew my own from old bedsheets) Parachute cord, a good knife, a steel & stone for sharpening, and a folding saw.
It is MUCH safer to cut a moose or elk into pieces with a knife and saw compared to using an axe. I have many old scars on my knuckles from handling moose quarters that were split with an axe. The bone shards are sharp and dangerous. Infected cuts on your hands are no fun in the bush. Believe me! Knife & saw are far superior tools.
To quarter large animals, you must cut down the backbone lengthwise. I never "quarter" big game any more. Cutting through all that backbone lengthwise is a waste of time and effort. And it damages the backstraps, the best cuts of meat.
I cut big critters into 8 pieces. The four legs are removed using the knife. The ribs are cut off with the folding saw and rolled up or deboned. The carcass is cut in half by sawing through the vertebrae between second and third ribs. The neck piece of a big bull moose carcass may need to be separated from the chest piece, if it is too heavy to pack with neck attached. I can normally pack two front legs, one hind leg, the loin, the chest/neck, and the 2 rib slabs as separate trips each. 7 or 8 trips in all depending whether you are also packing a set of antlers or not.
If you have a very long ways to pack, removing the bones is a great weight saving option, but it is harder to keep the meat clean. Meat ages better ( more tender) if it is hung for a few days in a cooler with the meat on the bone. If you cut the meat off the bone the meat will tend to be tougher.
Make sure the meat is hung in the shade to cool, and keep it clean! meat does not cool properly if packed and hung in plastic bags. Cotton is better, but many of the commercial "cheesecloth" bags are nearly useless for keeping meat clean. The holes are too big.
I come from four generations of butchers, so good meat care runs in the family. And delicious game meat is a fine reward for all the effort!
