Fifty-three pounds of polyethylene before a drop of water goes in: the 68H is the heavyweight of Ronco's 33 gallon holding tanks, carrying roughly double the material of its siblings. In a rotomolded tank, that mass is wall thickness, and wall thickness is what survives frame flex, hard miles, and the point loads of an imperfect installation. Fleet coaches, rental rigs, and full-timers who count highway days in the hundreds are the natural buyers.
The duty is unglamorous and specific: 33 gallons of gray or black water, never potable, hitting about 275 pounds when full at 8.34 pounds per gallon. If the extra blank weight is unnecessary for your use, the 15H is the standard-weight sibling, and the 52H offers a defined 46 x 16 x 12.75 inch envelope for narrow bays.
The rest of the waste range is at RV holding tanks, with the whole brand at the Ronco hub. One Source Plastics is an authorized Ronco Plastics dealer.
