First time using the 18.5" and tried some boneless chicken breasts following the recipe from the website.   They came out quite tasty but I never got the temp down below 310-315 degrees even with the vents closed 3/4.
I can't swear to the accuracy of the dome thermometer but it does occur to me if the .5" a gap in the side door it could be pulling in more oxygen and keeping the fire hotter than it should be.
