Normally we have decent hanging weather during Michigan's fire arm and muzzle loader season. there are problem days during the Oct. bow season how ever. One year at our UP deer camp it was in the mid 70F range during the day so hanging wasn't some thing we did like normal. since we were 6.5 hours from home we took two deer to a processer there. We were very disappointed with the results, very little meat we felt for the size deer we took in and lost set of antlers. We vowed never again. We bought a used fridge at an estate sale that with the racks out will hold 3 180 200 pound deer skinned. We made a rack to hang them from and can keep it a steady 35F. after a few days hanging we will cut up the deer and package it then it gets frozen in the freezer compartment. We did decide that the next fridge we buy for this will be a side by side for more freezer space.
You can buy a used fridge at a estate sale pretty reasonable as well as a freezer.
