So I am about 35 minutes into my Mash, and at about the 15 minutes Mark I was wondering why my rectangular cooler was losing heat so quickly today. It wasn't normal to be losing almost 3 degrees in less then 15 minutes!!! I took off the Blanket and backed off the heater from the cooler and I noticed the Culprit. The cooler is Warped. It is losing its shape and the front wall is pushing out from the pressure and the heat. Hence, the lid has about a Half inch opening along the whole Front Wall. The cooler is over 15 years old, so she has done me well. What I need to know now is this. Where can I get a 10 Gallon round cooler from this week? Anyone have a line on some deals out there?
