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...
From my days of Backpacking and canoe camping (9still do that) I plan the meals and put each meal in a zip lock or vacuum seal, then each days food goes into a larger zip lock bag so all three meals are in a bag and labeled, I pull out a days complete meals each day they are labeled for. We usually plan to eat out once a week for a break. I do keep all my spices etc. and some staples in the RV and enough canned stuff for a couple of standby /emergency meals are also kept there.
