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...
I bought a portable ice maker from Target for $125 on sale (normally $159). Sits nicely behind the sink/faucets and gives us just enough ice. The younger kids love watching it dump the ice into the holding basket. :)
