Toilet drain and water supply lines. Note: The battery charger is a temporary DC supply system for the build. When the build is complete the battery charger is replaced by Deep cell RV batteries which will occupy this area. (Update April 06- battery cannot be inside the RV! Gas venting from the battery is caustic) The DC inverter will be located here along with a storage bin that pulls out. The bathroom vent will be built into the raised platform floor next to the toilet and the hose will port bad air out the electrical access port on the side of the trailer.
