Ronco Plastics 14H - 26 Gallon End Dump RV Holding Tank With Rails

Dump geometry is the quiet reason waste tank replacements go sideways, and it is the reason the 14H exists as a distinct 26 gallon molding. Its outlet is configured for an end dump, valve at the end of the tank where rear-plumbed coaches need it, and its sides carry molded rails, integral flanges that accept straps or brackets so the tank supports itself against its mounting instead of depending on a fabricated cradle. If the tank you removed had flanged edges and an end-mounted valve, match those features, not just the gallons.

Capacity is 26 gallons of gray or black water, never potable, in a blank of about 26 pounds. Loaded weight is roughly 217 pounds at 8.34 pounds per gallon. The plain-bodied alternatives in the same size are the 54H at 28 x 22 x 11.5 inches and the square 62H at 24.5 x 24.5 x 11.5; one size down, the 45H covers long shallow bays at 74 x 15 x 8.25.
