Ronco Plastics molds two different 7-gallon RV holding tanks, and the 19H is the one you buy when the other shape loses. The 7-gallon 9H measures 30 x 9 x 11.25 inches - long and narrow; the 19H is a 13 lb molding in its own proportions, and the drawing below is the fastest way to see whether it clears your bay.
Both are strictly waste tanks. Gray water from a galley sink, black water from a cassette or compact head - about 58 lb when the 7 gallons are full - but no drinking-water claim attaches to either. The one-piece rotomolded shell has no welds or seams to open up under vibration.
Since 1974 Ronco has built these in Tustin, California, and every tank gets its fittings installed at the plant to your order, spin-weld or threaded. Print the drawing below, mark your fitting locations, and it ships plumbing-ready. If a small tank in a flatter shape suits better, the 9-gallon 35H at 29.75 x 22.5 x 8 inches spreads its volume thin; the complete set is under RV holding tanks, alongside the rest of the Ronco Plastics catalog.
