Are the lids actually attached to the kettle with a hinge on these models? Or does it just give a place to place the lid when you open it? I couldn't quite understand from the pics I found. Would be nice to have a hinged lid sometimes.
However, I read that if you place the lid flat on the ground while adding new coals, etc, that it will retain heat inside and come back up to temp more quickly. Any truth to this?
