Howler,
Yeah, we go for the "power elk camp" set up, although our spike camp (about 4 miles or so back in) can be carried in or out on one horse. We find generally if you are in it for the long pull and "come thick or thin" that the heavy duty camp to "recharge" in is a competitive advantage. (BTW, we saved $800 last year by butchering our own.)
Otherwise everything you saw arrives and leaves in these three vehicles...
[You're right, the word uhaul is in there and quite appropriate!]
I know from some of your descriptions that you enjoy taking some of the comforts of home along as well.


Good Luck and Good Hunting,
EKM
