Ronco Plastics 23H - 28 Gallon End Dump RV Holding Tank With Rails

Ronco molds exactly one 28 gallon holding tank, and the 23H is it, sitting alone between the four-shape 27 gallon family below and the rail-equipped 29 above. Solitary sizes usually trace back to a specific OEM contract, which is good news for the owner of that coach: the tank that fits is still in production, decades later, from the original kind of maker. The blank runs about 32 pounds, on the substantial side for its class.

Duty is the standard H-series brief: gray water or black water, never potable, with a full-load weight around 234 pounds, 28 gallons at 8.34 pounds per gallon. Check straps, cradle, and floor before the swap; the tank is usually the healthiest part of a thirty-year-old installation.

If 28 gallons was approximate, bracket it. The 47H holds 27 gallons at 43 x 22 x 11.25 inches, the 27H adds molded mounting rails at 29 gallons, and the 22H reaches 30 gallons at 39 x 25 x 12. Full range: RV holding tanks. One Source Plastics is an authorized Ronco Plastics dealer.
