I've seen new trailers that were set up with a valve, a 3 way maybe, where once you are hooked up to city water you can set the valve to fill the onboard fresh water tank, or direct feed the plumbing, sinks, toilet, water heater and even flush the black tank. No separate fill port. We were next to a trailer with that set up, and the valve screwed up and kept sending water to the tank, filled it, and then water ran out the overflow on to the ground. Calls to the camper dealer resulted in "bring it back for a valve replacement"
