Of all the Gosh awful things. Spam counts as an emergency protein source when dried liver supplies are gone. Refrigeration is not necessary for many foods over a three or four day time period unless the temps are hot. If you are in to salt and nitrates simply get a Va dry cure ham. What you do not use will still be good the next decade and no refrigeration. There are old style fermented meats that keep well w/o a fridge. Even dried beef. I am surprised you didn't include a can of pineapple and make Hawaiian pizza in your Dutch oven with the spam. One of my favorite parts of an encampment is the food. Wild goose, stuffed with apple and rice roasted over hot coals and slathered with orange sauce, planked salmon steaks, hearty stews of savory beef and lots of sweet tender carrots., A whole roasting chicken, lightly sprinkled with Old Bay and smoked with hickory chips., A low country boil, of crab, shrimp and clams with clarified butter on the side, corn bread, cranberry scones, sweet potatoes cooked right in the coals. Baked apples glazed with maple and walnuts...followed by a mug of hot spiced and spiked cider or gluhwein............ And you WANT to eat Spam??? Heathen!
