Sixty gallons in a compact, deep-bodied molding: the Ronco Plastics B474 stacks its volume vertically rather than sprawling, which suits lazarettes, cockpit lockers, and machinery-space corners where floor area is scarce but height is available. At 49 lb empty, it is remarkably light for the capacity.
As with every dual-role B-series tank, the B474's job description is written by its fittings. A fresh water order yields a potable tank in food-grade polyethylene; a waste order yields a large gray or black holding tank. Either way, Ronco's plant installs each fitting per order, spin-welded or threaded precisely where you mark it, which is what makes a deep tank plumbable at all: the pickup goes where your pump needs it, not where a factory guessed.
Respect the full load: 60 gallons of water is about 500 lb at 8.34 lb per gallon. Print the dimensioned drawing below, confirm the tank drops through your access opening, then finalize ports in the on-page fitting planner.
