This is the official product video for the Ronco Plastics 78H - 21 Gallon Plastic RV Holding Tank. Full specifications, dimensions, and live pricing are on the product page.
In the hush beneath a coach, a reservoir waits... Ronco’s 78H is a 21 gallon RV holding tank, molded for gray or black water collection beneath a trailer or motorhome floor. It handles waste — not potable water — and ships at 34 pounds. The tank body is rotationally molded as one seamless piece at Ronco Plastics in Tustin, California, where polyethylene tanks have been in production since 1974. Seamless construction matters most in waste service... a joint failure is not a mess you want to discover on the road. Ronco installs fittings per order: spin-weld or threaded, located to your specification so inlet, outlet, and vent line up with the coach’s plumbing.
