We have a 2018 2108 that we are prepping for our winter travel down south. One thing we added was a hose under the sink connecting the shore water line to the water tank line, with appropriate valving, to allow us to fill the tank from shore water. I removed the floor of the sink cabinet and replaced the mounting screws with magnets to make access to the valves easy. Now when we have shore water I just have to open the valves and wait for water to burp out of the tank fill.
When I'm hooked up to what you are apparently calling shore water, I just make sure my electric pump is off, hook up to exterior water and the water comes through everything fine. There was no need to fill the water tank all the time. The water tank is for boondocking when you don't have access to a exterior water supply. Or am I misunderstanding what you are doing?
OK, that makes sense, it's just a fill valve from the normal exterior water with the valves inside the trailer. Normally at most we keep about 1/3 tank of fresh water for toilet stops.
I usually keep about 1/3 of the fresh water tank full just in case the campground water gets shut off or we need a bathroom break on the road. My fresh water fill is on the opposite side of the trailer from my water hookup.
I think dragging the hose over to the fresh water filling port is easier than crawling around under the sink and turning valves, but that's just me.

The valves that are the bypass ones on my 1790 are under the bed. Then I have a hot/cold drain valve on the bottom of the trailer that us also used to drain the lines with since they are the low point of the water.
