Geek, I am certainly interested in your data. I drive a jeep, and the temps are pretty extreme. Any food storage for me within the jeep is limited by the space allowed-the temps can get HOT inside the cab, as the only thing between the sun & the inside is a thin layer of vinyl/canvas. Or, if the top is off-exposed directly to the sun. Either way, they are exposed to fairly significant extremes, and data like this would be valuable to me. Thanks in advance for this!
