I got through to the factory today. Spoke to a very helpful fellow. He wasn't aware of a history of the problem that I described but confirmed that there is a pressure regulator in this coach. It is behind the water inlet fitting and as with all things mechanical, they do go bad. He is sending one to me no
questions asked. I can either have the local dealer (the one that told me it didn't have one, nor did I have an accumulator, which is behind the convection oven) install it or any one else that I trust and send him the bill. In addition, he is going to check units that they have and see what flow they flow and let me know early next week. I really can't beat that for service! Last night, while in bed, I was telling my wife what the net members had said and what I had done to come to the conclusion that the regulator may be bad. I realized that there is a host outlet fitting on the same line as the fixtures. On the unit side of the regulator. I jumped up and got dressed (much to the surprise of my wife) and went out to hook up the supply hose to that fitting.

It had a anti-siphon device that I had to remove with a vice grip but in the end I was able to attach my supply hose with the aid of a double female hose fitting. Bottom line, I was able to fill my gallon container from the kitchen in 50 sec (1.5 gpm,up from .85) and the shower 53 sec (1.13 gpm, up from
.78 gpm). Getting closer to rinsing the soap from Mama's hair. More to come after I hear from the factory next week.
