Nice job on the video, I know you will really enjoy your cooker as you get to use it more and more. I just use a chimney for start up, and load up the chute after I've dumped in the hot coals. I have a rebel 17 and love it, I have to agree that for me anything short of 6" clearance really limits what you can cook on those lower shelves. You can always take one out which is what I would do, for loading one up with big meats. But it's nice to have that extra shelf for stuff like ribs, and man these verticals are a rib cooking machine.
It's all about the Meat!
