The RVB156 is one of the longest-standing part numbers in Ronco's 50 gallon RV fresh water range, a light-duty potable tank that has gone into decades of motorhome and trailer builds. It ships at approximately 92 pounds, placing it in the heavy-wall tier of the class, built for tanks that get installed once and forgotten.
Every RVB156 begins as natural FDA-compliant polyethylene at Ronco Plastics' rotational molding plant in Tustin, California, where tanks have come off the line since 1974. Rotomolding produces the shell in one seamless piece, and the pigment-free resin leaves the wall translucent, so a glance at the tank tells you how much of the 50 gallon supply remains.
The finishing step is customer-specific: Ronco installs spin-weld or threaded fittings at the locations your order defines, its standard on all tanks, which makes the RVB156 as suitable for duplicating an original tank's port layout as for a clean-sheet build. Where a drawing is shown it depicts the blank molding. OneSource Plastics supplies it as an authorized Ronco Plastics dealer.
