Fresh fruits such as apples, oranges, peaches and grapes are ideal for car camping trips. These fruits keep well in a cooler and will not deteriorate in hot weather. Wrap fruits in plastic wrap or put in a plastic bag to protect them from melting ice. Apples, oranges and peaches will stay good at room temperature for three to four days.
Ideal vegetables for car camping include carrots, celery, cucumbers, zucchini and green beans. Choose vegetables that have just ripened to avoid spoiling. Vegetables keep best if they are kept in a cooler.
Hard cheeses can be taken on car camping trips without a cooler or source of refrigeration. Soft cheeses, however, require refrigeration. Cheese is a good source of protein for the road, and is also quite filling.
