The Ronco Plastics B398 is a 16 gallon B-series molding at 24 lb shipping weight, the light-wall option in a capacity Ronco molds in several shells. Choose it for protected installs where handling ease beats armor: inside a console, under a v-berth, in a camper cabinet. The dual-role design holds: potable fittings yield a food-grade fresh water tank, waste fittings yield a compact gray or black holding tank.
Full weight is about 133 lb at 8.34 lb per gallon, modest enough for light framing with proper base support.
Because fittings are installed per order, the tank arrives ready for your exact plumbing. Print the drawing below, mark your fitting locations, and use the fitting planner on this page to specify sizes and styles; the factory spin-welds or threads them to your marks. That is the Tustin, California build method Ronco has kept since 1974.
