I had some thing over 400lbs of meat from my last NB moose and he was a young bull. I had him cut and wrapped in NB and the packages were frozen in the open coolers in the butchers walk in freezer.
I used 4 Coleman 150qt freezers and there would have room for some ice, but I didn't use any as its just 10 hrs from NB to home for me.
I would say to the OP that 2 150qt freezers would probably do, but three would be sure and leave more room for ice.
