I'm also waiting on my dome thermometer but will just be using a candy thermometer today.
So as I understand it, you are creating an air gap under the ash tray thus decreasing the distance between the coal basket and ash tray if you are trying to maintain the 23 to 24 in distance to the grill (which should be 7 to 8 in below the lip) . Are you also raising the grill? I would think that when the ashes build up in the tray that would be sufficient insulation.
