I do the following on our river trips:
- cover the top of the ice chest with a white, wet, towel over an insulating cover.
- inside the ice chest, cover the top of most of the food with a reflextix type space blanket with our lunch on top. So when I open the ice chest in hot weather at lunch, we don't let in a lot of hot air.
- a full ice chest is a happy ice chest
- if the ice chest won't be opened for a week or more, duct tape the seal closed.
- use block ice rather than cubes.
- make my own block ice in my freezer rather than use the commercially available stuff which is just compacted crushed ice anyway.
- while traveling to the river, wrap the ice chest in a sleeping bag.
- pre-cool both ice chest and food before loading
