I have just a standard two-burner Coleman stove. I also have cast iron griddles that seem to fit nicely on top. Should I place the griddle on the metal pan/pot supports above the burners, or should I remove these supports? Would the latter cause too much heat, or restrict air flow?
PP, if I am reading you correctly we have always used the metal grid support above the Coleman burners to hold the griddle, pots, pans or etc. I do not know, but sitting the pan or griddle directly on the flame burner bowl might snuff out the flame, or at least make it impossible to gauge the flame height/heat. Once the cast iron got hot it didn’t take much flame to keep it at the desired grilling temperature.
For group trip short order breakfasts the wide Lodge griddle fit across both burners. Since the left side auxiliary burner is always weaker than the primary right we had two temperature griddle sides and could move things back and forth as needed.
Our 2-burned griddle is like this

But it has a grease trap lip indentation at the front. I think it is a Lodge, but I’d have to go check.
Actually I’d have to go find it and check. That thing was wonderful when we did group trips with a 2 burner Coleman and short-order chef friends, willing to man the morning griddle and make (and keep making) eggs, sausage, pancakes and homefries. Not to mention corned beef hash, fried green tomatoes. . . . .soft shell crabs. . . sometimes that was a two-person or even two-stove operation, but dang it was fun to watch in action. And delicious.
My solo oatmeal, breakfast bar and instant coffee is sounding pretty weak.
