Great job Mike ... I'd hammer both!!
Like Steve mentioned - cooking different proteins can be a challenge.
Not really my experience. I loaded the basket full of coals. Hung them both at the same time. Waited 1 hour. Cracked the lid for 15 minutes. Pulled the ribs. Then let the chicken finish lid off for 5 minutes. Worked at great. Ribs tasted good to me.
Perhaps more than one rack of ribs or chicken would create more of an issue...
