ICE

We have had both an Igloo and Coleman ice chest which keep things frozen or cold for at least five days. We try to open them just a few times a day. We put the ice chest in the back of the truck and when we arrive there is still ice and frozen food in the bottom. Both are over ten years old so I hope they still make them that good.
The few times we take one with our TT we make sure that it is sitting in the shade. Our freezer is quite large so we seldom take it to a campground.
