Being a prepper myself, I'd see no problem going just a few weeks with no refrigeration. We had a very rough period where we ate most of our meals out of our food storage for eight months! (no, I don't recommend it), lol. You could, however, start out with a cooler with ice, pack it with lunch meats, small condiments and salad bags until the ice melts, then move on to the freeze dried foods. Mountain House has a pretty dang good Chili Mac in a pouch that's really tasty. The spaghetti, however, is nasty. As for the eggs, if you coat them with mineral oil, they'd be good for about nine months, unrefrigerated. The powdered eggs are flat out horrible, and I only use them in baking. That all said, be sure you have a lot of water with you in order to rehydrate everything.
