Having just picked up a Diamondplate pit 60, ten times larger than the old Chargriller, and only doing several smaller (One or two item) cooks, trying to get familiar with it....I was wondering what would happen to chamber temps, and cooking times when you filled the thing up?(supposin' a guy could afford to). I thought that maybe more mass would mean more heat retention and quicker cook times? But it never came into mind that humidity levels would change as well......Thanks for the post. Great idea.
