I wanted to post pictures for anybody who hadn't tried this out and wanted to. I tried it out tonight, and it worked perfectly, so far as a newbie bbquer as myself can tell. My girlfriend said she wants all grilling done on this instead of my gas grill now lol
Just remove the middle section, and put the top grate on top of the charcoal ring, and you're set. If you put the top on though, the handle gets awfully hot, way hotter than when you're smoking.
I know there's another way to grill on this by keeping the middle section in place and removing both the bottom cooking grate and water bowl and cooking on top. I'll try that and post it here next time I grill.
I'm sure plenty of you know how to do this, but I know it's helpful to me to find the same information in multiple places.
