We are planning a cross-country road trip in July (since our B2B DCL in Europe is toast). We have a child with a severe food allergy, so we want to prepare frozen meals at home and bring them with to the rental houses, as to minimize cross contamination. We need a really good/reliable cooler that we can throw in the back of the vehicle and trust that the frozen food will stay frozen for 8-10 hours. We are looking at the 45 quart Yeti or Rtic. Any suggestions or personal experience with either, or even something else? Thank you!
