That's a good video. I like his detail. Gonna share it with a buddy of mine who has a "Bigger, Better Basket." In other words, just like the guy in the video, he would not be doing a snake.
You'll add charcoal throughout, because lump burns hotter/quicker. Have water in a pan; you'll need it to stabilize the temp with that fuel. I'd use the black ... I'm not a fan of banking coals, ever, on a colored grill!
My understanding of doing this on a 3-wheeler is to completely close two vents and just work the other, under the fuel. You won't even have to open it up fully.
