Montecarlo from Gala RV
An interesting aspect of the layout is the Fresh 45 Gal/170 L tall and slim tank that is located in the wall cavity between the sink and the shower. It helps stabilizing the potential (375 lbs) weight of the water when the vehicle is in motion.

I did some screen captures, with some specs.
From my Gala RV FB album I did 9 month ago, when the vehicle got unveiled, and completed with photos from the RV show in Montreal:
Text in red: The Fresh tank is positioned vertically in the wall adjacent to the bathroom, in front of the side (sliding) door.
