Texsport Heavy-Duty Swivel Grill
We spent our first summer camping in a tent and the majority of the campgrounds we stayed at did not have charcoal grills. Our first purchase for cooking was a campfire grill that can be used over the campfire. While we now have a pop-up complete with an indoor stove and outdoor grill, we still use the grill frequently and actually prefer some foods cooked over the fire. Some campgrounds do have fire rings with a similar grate attached, but many do not so we always bring ours along.
