Looks good!
Is that Royal Oak lump charcoal in there? That's what I've been using in my WSM for almost a year now so I'm curious how you found the lump charcoal. Were you using briquettes in your WSM before this?
Yes it is and the first time so.... I'm still learning it, I used briqs to start it, my temp started to rise once the lump started so I'll start watch my temps better. I have been using Kingsford Professional briqs before this and have been satisfied.
RO lump is my preferred fuel for most all of my 18" & 22" WSM and kettle cooks.
I use two char grates in my WSM, with the second one rotated 90 degree to the first. This prevents the smaller pieces of lump from falling thru and helps maintain a good bed of coals.
Cowboy and Western are junk lump coal. IMHO
