Seventy gallons splits the difference between the everyday RV fresh tanks and the true expedition sizes, and that is exactly where the RVB296 sits - Ronco's B-296 L.D., a light-duty molding for coaches that boondock hard but cannot give up the bay space the eighty-plus-gallon tanks demand. At 50 lb shipped, it stays honest about weight while carrying a genuinely large water load.
The polyethylene is translucent natural resin, FDA approved for potable water. You will appreciate the translucence on day four of a dry camp, when a flashlight against the wall answers the only question that matters. Like every molding in the book it ships as a configured blank: Ronco spin-welds or thread-installs your fittings at your marked locations. Print the drawing below, mark supply, fill, and vent against the coach's actual runs, then commit the layout in the fitting planner on this page.
Ronco has rotomolded RV tankage in Tustin, California since 1974, and the light-duty wall spec is the fruit of that tenure - enough material for the job, none for show.
