The 41W is the tank you buy when the space came first: 17 x 12.75 x 10 inches, 8 gallons, roughly the volume of a milk crate. It fits standing up in a cabinet, lying down in a drawer bay, or tucked vertically beside a water heater - and because it is compact in all three dimensions rather than just one, it adapts to odd spaces the long flat tanks cannot.
Ronco molds it in the Water / Waste Holding Tank series: order fresh-water fittings and it is a potable supply tank in FDA-compliant polyethylene - a real fresh system for a teardrop, van, or small workboat; order waste fittings and it is a compact gray catch that hides under the sink it serves.
Seven pounds empty. About 67 lb full, with water at 8.34 lb per gallon - the friendliest mounting problem in the catalog. When 8 gallons stops being enough, the RV water tanks category scales the same idea up through every size class, and RV holding tanks does the same for waste. The whole family sits together at the Ronco Plastics hub.
