For anyone on the fence, I put 40 pounds of ice from one of those bulk Twice the Ice places (very wet ice, not fully frozen). As of yesterday evening, it still had ice at 108 hours into the test.
My guess is it will last around 120-130 hours before being completely melted. And that is without prechilling.
