The Mobile is a self-contained toilet rated for use on boats and motor vehicles. It eliminates the need for pump outs, and with the ability to run off of a 12v or 110v power, it can function when the vehicle is both stationary and in motion. The Mobile is engineered to accommodate for motion with mounting brackets, a secured and sealed finishing drawer, and a fold-up footrest. Similar to other Sun-Mar units, there is a safety drain built into all Mobile units. This is recommended in all installations. The Excel is available in two colors – white and bone. Prices do not include tax and shipping costs.
