Hey Trace, I dont see a video attached to your post. Is the leak coming out of the pan that covers your black/grey tanks? I'm having the same issue on our 2001. Finally broke down & pulled the support pan off to expose the tanks & valves & found cracked adapters. (the piece that mounts the valves to the tanks )
I don't know how similar your 2012 setup may be to our '01, but your welcome to come see what I'm working with while I have the pan off. I'm on the East side of Tucson. PM me if your interested.
I'll be posting a few pics & progress reports here also.....
