1) Ameristep non-typ is VERY portable- going in on your back as a backpack. Lightwt, canted wheels, . . . I have hauled out a few 200#+ field dressed deer with it. Works great.
2) Another option that I have been doing often the past few years; just quartering them out like the Fred Eichler vid on elk. I do that on deer- no gutting, deer is on the way out in 20 minutes. Your "deer cart" is 6 oz. - called a pocket knife! (By the way, I have been deer hunting 40 years- and this was never the tradition from the east/midwest. I think of the deer I dragged out of thick cedar swamps- just can not believe how stupid that was!)
