So we just went on our first week long camping trip with the family to a new camping "resort" in the area. Loved it, the place was magnificent! We packed our travel trailer full of food and snacks...
As for food stocks. I always make sure there are 2 meals(breakfast and dinner) per day, and junk/snacky foods for lunch or whenever. I never get too serious about meals. as long as there is food to eat
