The family and I have been enjoying our time with our 1999 Coachmen Mirada 300QB, but I have been bothered (nay, plagued with doubt and curiosity) every single time I have to use the infamous "water valve panel." I've searched several times (in vain) to find a definitive explanation of the inner workings of this system, always resulting in an empty-handed retreat. Well... I'd finally had enough, and dove in headfirst to uncover the decades-long mysteries that veil the Coachmen Mirada 300QB plumbing.
I know that this may not interest many folks anymore, simply due to aging of these coaches. I know that this is 20 years too late. I know that some folks are content "paying no attention to the man behind the curtain" that pulls the levers and makes the Mirada water flow. But... for the scant few individuals who are still care out there; for the stragglers who are buying these good 'ol coaches and keeping 'em alive... I present to you...
THE DEFINITIVE COACHMEN MIRADA WATER PLANEL EXPLAINED.
(jpgs to follow; see attachments for PDFs of general system and valve layout, routing of water under common use positions, and even a "bonus" setting I use for sterilizing).
Seriously... I hope this helps some of you!
