Cast Iron Camping
Hello, welcome to the forum.
Cast iron is tough, heats evenly, and can last a lifetime. If its properly seasoned a cast iron skillet or pot will resist rusting and provide a non stick surface. A small downside to them is they are heavier, and require a little more upkeep.
Stainless is also heavy. A lot of the stainless pots/pans tend to be thin and you will easily burn your food that way, and the thicker ones tend to not heat evenly. In my opinion, stainless is a good alternative if you do not want cast iron, you want easier cleanup, lighter in weight, and are not as concerned about even heating.
