One of the things I hate when camping is having to find ice every couple of days. A friend of mine turned me on to a cooler insulation insert called the KoolerCap. She told me that my ice would last...
My husband bought the smallest freezer Wal-Mart had, it holds 12 full size ice treys and a few items like frozen potato's, meat, etc... I see a lot of people with a fridge sitting outside but we have a freezer. We are good about dumping the treys so we never have to go to the store for ice, it pays for itself very quickly.
