Here are a few photos of the SMB layout beneath my Gaucho. I added a house battery main disconnect switch, and a Blue Sea 7622 with remote. I located the remote by the drivers seat. I also added a shunt so I can monitor charge and discharge of the house battery. Routing of the waterlines by SMB within the walls and under, is still a mystery to me.
