Boondocking math is unforgiving: every day off-grid is a fixed draw of drinking, cooking, and wash water, and the tank either carries the trip or cuts it short. The RVB327 puts 80 gallons of fresh capacity into a light-duty Ronco B-series molding, which for most couples turns a nervous three-day dry camp into a comfortable week. The trade is weight when loaded - water is 8.34 pounds per gallon - so plan the mounting location against the drawing before you commit.
The tank itself weighs 109 pounds and is molded in translucent natural polyethylene, FDA compliant for potable service. The translucency is a working feature, not cosmetics: you can read the remaining supply at a glance from outside the tank, no sender required. Ronco has molded water tanks in Tustin, California since 1974, and this molding carries that production history.
Because Ronco installs fittings per order - spin-weld or threaded, located to your marks - the RVB327 you receive is configured for your plumbing, not a generic guess. Print the technical drawing below, decide where fill, vent, outlet, and any auxiliary ports should sit, and run it through the fitting planner on this page. That is the whole ordering process.
