Every RVB484 that leaves the plant is, in a sense, a custom tank built on a stock molding. The blank - one of the larger fresh water shapes in Ronco's light-duty B-series, 135 pounds of translucent natural polyethylene - is identical from order to order. What changes is everything you decide: which faces carry the fill and vent, where the supply pickup sits, whether a sender port goes in, threaded or spin-welded at each position. Ronco's Tustin, California plant executes your layout at order time, the way it has configured B-series tanks since 1974.
That split between stock molding and custom configuration is why the ordering sequence matters. Print the technical drawing below first - it is the true footprint and the canvas for your fitting layout. Mark your ports where your plumbing actually runs, then work through the fitting planner on this page until the layout is final. The tank that arrives will match the paper.
The spec underneath is Ronco's proven potable recipe: FDA-compliant resin rated for drinking water, natural translucent walls that show the level at a glance, light-duty wall schedule for supported in-vehicle service. A large tank filled at 8.34 pounds per gallon is a genuine structural load - plan the mounting floor accordingly.
