I store my stuff in a detached garage in Texas so trust me I feel your pain. Been doing it for years and honestly the heat alone isn’t a huge problem for 1.4G consumer stuff as long as they’re dry. The bigger killer is temperature swings 鈥?when it cycles hot/cold/hot the cardboard can absorb moisture and then you got issues. Pallet + dehumidifier is smart. I also throw a cheap thermometer/hygrometer in there just to keep an eye on things. If humidity stays under 60% you’re probably fine.
