When a family of six dry-camps for a long weekend, the holding tank is what ends the trip early. The 91H is the answer at the top of Ronco Plastics' RV waste line: 50 gallons, the largest holding capacity on this shelf, molded with a substantial 97 lb shell that is noticeably heavier-walled than the mid-size tanks.
Full, that is roughly 417 lb of gray or black water, and waste is all this tank is for - the resin package carries no potable rating and should never see the fresh side of the plumbing. The one-piece rotomolded construction has no seams to split under sloshing loads on rough road.
If 50 gallons is more than the frame bay allows, both 48-gallon molds - the 60H and the 92H - give up two gallons in exchange for their own footprints. The rest of the range lives under RV holding tanks, and the freight cost estimator prices it to your ZIP.
