Trionic’s Super Premium Holding Tank System is virtually odorless and eliminates the potential of a messy collapse. Rotomolded from virgin polyethylene, the tank has an extra thick 3/8″ wall and includes a raised vacuum relief valve with an easy-clean screw cap. This advanced construction allows the tank to resist collapse even if they venting system is clogged. The new tank also features a unique top-mounted hose connection system to remove standing sewage from discharge hoses; rotatable inlet and outlet and vent fittings; and an optional overboard discharge for an additional $30. Retails for $210-$690. For more information, go to www.trioniccorp.com.
