I am with you myredracer. that's why I do the best I can for us. and that's using bottled water. I have always said, we don't use that motorhome enough to feel safe about the waterlines. With municipal water lines, they are used frequently so things don't sit and grow. I agree with you, most rvers have no understanding of bacteria and its growth. Pluse, we just upgraded and a new to us MoHO and not knowing where it has been or how it was used , I choose to be as safe as I can be.
BTW, you can call me mywhiteracer. 79 L82 :)
