I had a 75 Taurus 23'. There was no plastic water tank, the water system was a galvanized tank under the front dinette seat on the drivers side. This tank was pressurized by a a small air compressor at the rear of the same dinette seat with an ordinary house hold light switch controlling the air compressor mounted to the front of the kitchen lower cabinets. There was no gray water tank, everything drained into the black tank. My bathroom ran across the back of the trailer with the bath tub on the drivers side.
