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.
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.
