I have a 4 door dometic refrigerator in my 2018 303 RLS that struggles to cool properly in high heat when the sun is beating on the slide. . I was wondering if anyone ever used these icepacks to help cool down the refrigerator when the internal fridge temps start climbing. My plan would be to leave a few of these in the freezer section to stay frozen and then drop them in the fridge when the internal temps start climbing
