Then stack them on top of one another and store them in freezer bags. By doing this a couple days ahead of time, the meat will be frozen and will keep the other foods in your camping cooler chilled. Another idea is to marinate chicken and store it in freezer bags also. Try to pack dry goods as opposed to fresh. Wash potatoes at home and wrap them in foil for baking instead of having to do it at the campsite.
Many vegetables are available in canned form, also ravioli and stews.
I found the best way to keep my breads and snacks fresh was to pack them in a rubber tote. This is a handy way to carry all of your dry goods instead of plastic bags. Coleman propane stoves are a great asset for camping. It is much easier to cook on these since you can control the heat settings. Remember to bring a large plastic tarp and rope for overhead if the weather turns ugly.
