You know this make me think of something that MAY help others. An acquaintance had what I thought were 2 big chest freezers but, she said one was used as frig. Apparently the thermo went out and they replaced with one to set at frig temps, not freeze.....?????.....anyway, with such freezers being seen for such temp issues, it may be a way to make a huge super cooler. ?? I'm not an HVAC person but, I know it CAN be done.
Oh, they use theirs for excess milk, vegs, etc. It was big but, I have a small chest freezer that would be ideal for use as a very large cooler. PLUS, it cost less new than some of the large coolers. You cold even drop a carcass in at freezer temps and chill that pork. Cut it off, turn down low, etc. ????
