The Ronco Plastics B394 is the heavy-wall 28 gallon tank in the B-series, shipping at 87 lb where lighter moldings of the same capacity weigh a fraction of that. The extra polyethylene goes into wall thickness, and it shows in how the tank shrugs off pounding hulls and rough roads. Dual-role by design, it takes potable fittings as a food-grade fresh water tank or waste fittings as a gray or black holding tank.
Filled, it carries about 234 lb of water at 8.34 lb per gallon, a load this wall section handles with ease between reasonable supports.
