  In the bathroom, there is an element under the floor plus the one on the wall below the shower handle. I don't know direction of flow, but I could always feel the heat in the bathroom first, also in the cubby on driver side near expansion tank. The others were much more elusive.

  @MuttonChops Other than the location of the expansion tank, which is in the closet in my 2019 400, the diagram is correct from what I have inspected. In the bathroom proper below the water controls is an arched metal pipe that heats that area, and then it exits to the expansion tank and from there to the boiler. Under the bathroom floor in mine is a typical aluminum convector. I have one bleed point at the arch in the bathroom. I know that newer models added bleed valves at other locations. Your flow is correct for my unit.

  Don’t forget about the manual bleeds on the rear/bed convector, the kitchen convector and the passenger dinette.

  Thanks to everyone for the comments/clarification.
  The link @pthomas745 proved to @bergger 's detailed reference pictures was very helpful.
  
  I've got what I need for now - - - will update/customize if/when a 400 is purchased.

  There are 6 convectors in a 400 . You missed the one that is adjacent to the cool cat area in your final drawing - Left side , front of the 400 - dinette seat area . The heat from that one goes up into the window cavity . 
  
  This thread shows pictures of each convector quite well .
