Ronco keeps four different 33 gallon holding tanks in production, and the 15H is the first stop in that family. Thirty-three gallons is fifth-wheel and Class A territory, the gray tank that has to swallow a week of showers, and the four shapes exist because big coaches package their waste bays in every configuration imaginable. This blank weighs about 29 pounds and serves gray or black water only; no potable use.
The load figure for mounting design is about 275 pounds full, 33 gallons at 8.34 pounds per gallon, cycling every trip. Confirm the envelope against the dimensioned member of the family first: the 52H at 46 x 16 x 12.75 inches if your bay is narrow and deep. Then the specialists: the 20H side-dump at 63 x 20.25 x 8.5 one gallon up, or the wide flat 3H at 64 x 32 x 8 two gallons up.
Full family: RV holding tanks. One Source Plastics is an authorized Ronco Plastics dealer.
