You're correct, a CLAM is a little warmer inside in hot weather because of the fine mesh...the mesh is not much use to keep out the cold or wind in freezing weather, though, so the wind panels are helpful then.
And since it is labelled against cooking inside, you cook inside at your own risk. On the very rare and wrong occasion, a small butane or propane
cooker can "flare up" sending a brief flame five feet high.
Some canopies have fire ratings that allow for a brief flash of fire, some don't. Pay attention to any warnings. Use a small table outside the CLAM for your little stovetop and bring your cooked food inside, maybe.
Oh, goodness, I sound so bossy today. Sorry. Hoping that you enjoy your CLAM!
