Wife got me the 18.5 inch for our anniversary. Just got into smoking about 1 year ago and had been using the webber kettle grill. What a surprise, I'm really excited to have so much more smoking space and I'm assuming the temp is a little easier to control. Been doing a lot of reading on this site and watching youtube vids and still have some questions. Can you rely on the built in lid thermometer? I do have a Maverick dual probe if needed. I figured if I'm doing 2 butts I should have a probe in each and that would leave me with only the lid thermometer. Just not sure, hopefully someone can help. On my WSM I see a rubber type plug on the side with a place to stick in a thermometer probe and a slit to stick in the digital probe which seems really cool. Just going back and forth on the sand, water, ceramic brick for the water pan. So many opinions on that. Also trying to figure out the best amount of charcoal to use and then which method of lighting is best. Again, so much debate. Any tips are appreciated!
