We just bought a 2018 Coachman Catilina to place permently in the back yard. I have questions, I have had two RV techs stand me up, so I hope you can help me. If I read the manual correctly, I connect my waterhose to the rv, where is says city water, and let it run. Then go inside the rv and open all the faucets and wait for water to begin to flow from them. My questions..... Do I ever turn the water hose off or let it run full time. And, by turning the hotwater heater switch on in the fuse box, is that all thats needed to turn it on and when do I turn it on, once water is flowing from facets?
