I'd make a guess that the dealer installed the remote display in a spot where it was the easiest and least amount of work.
I mounted our remote display inside a cabinet above the dinette, at the top of the rear wall. I just open the cabinet door to view the display. I found the scrolling very annoying and distracting, and the DW even more so. Have a bunch of other LED displays and indicating lights plus the blue glow of the radio and it looks like the inside of a space shuttle and don't want another one, esp. if it blinks non-stop...
I installed an LED voltmeter and ammeter (30 amps) on the wall near the entry door and only need the EMS display for error codes should the EMS sense a problem. The non-scrolling displays are sooo much easier to view and don't need for the readouts to scroll through the sequence to see what you want which normally would be just the voltage. I still need to stick a copy of the error codes on the wall beside it so I won't need to go searching for the manual if needed.
Don't know where your EMS is, but without too much difficulty, you can run wiring inside interior walls, in the hollow cavity under cabinets, in ceilings, inside dinette seating, under shower/bathtub, etc. Then you could relocate the remote display to a more suitable location (limited by the cable length).
One thing I don't like about the PI remote display is that it is designed for surface mounting only. Would be nice if it could be flush-mounted on a standard outlet box cover plate so it could be installed on a wall.
