The water heater is a Truma Aqua Go I believe. It is standard equipment in the View/Navion 24G and optional in other floor plans. It has a recirculating pump to get the hot water to the far end so no water is wasted. That can be turned off for 'Economy' mode.
The toilet is an electric macerator porcelain type. What I have now sits right over the holding tank; simple like an outhouse.
