Abstract
Abstract A waste fluid holding tank for use with a camper mounted on the bed of a pickup truck. The tank is constructed to fit within an open space on the bed of the trunk substantially in line with a wheel well cover which extends into the load-receiving region of the pickup. The space in which the tank is received is bounded on one end by the wheel well cover, on one side by a side wall of the pickup, and on the opposite side by a lower side portion of the camper. The tank has an inlet opening adjacent its bottom and a vent opening adjacent its top. An elongated drain conduit is connected at one of its ends to the inlet opening and is detachably connected at its opposite end to the drain in the camper. A vent conduit is connected at one of its ends to the vent opening and has such length that its other end may be secured above the drain in the camper when the tank is below the drain.
