location of drain plug on 2012 coachman freelander

I am not a Class C owner, but I have recently been helping a friend diagnose this same problem on his Coachman Freelander in order to empty his freshwater tank. After reading “KennyBoy’s” post below and now this post, I am scratching my head as to why Coachman has designed such a convoluted, complicated system to accomplish the simple task of emptying a freshwater holding tank. Had the guy who designed this particular feature ever gone camping before? It makes me wonder.
