@lemisfits Do you have the top vent 4 to 6 turns open? I believe I've read the coco char is hard to light. Have you tried starting some Rockwood then adding coco char on top?
I use a chimney. For hot cooks I'll start by digging a hole (so to speak) in the middle of my charcoal and start the chimney in the hole. Once the charcoal in the chimney is going I'll dump it in the hole and add fresh charcoal on top. I have no problem achieving 700°+F. For the vents I open the bottom fully and 4 or so turns on the top vent.
Welcome @Scottishhammer I also have 16" and 23" and it is a great combo. I agree with basket splitter, rotisserie, cover, and stone. I don't have the cold smoker...yet. Whatever you decide on you can't go wrong.
@Flemming nice video! Looks great in it's new home. Nothing better than moving a new KK around with heavy equipment!! How much time passed from the time you took delivery at the dock till the time you put the cover on at the end of the video?
