A reliable holding tank is the backbone of any RV's waste system, and the Icon 12428 (model HT499-RE) is built to last. Molded from heavy-duty high-density polyethylene, it offers a generous 76-gallon capacity in a low, wide format that tucks neatly into the underbelly of larger rigs.
The recessed drain sits flush with the tank body for a clean plumbing connection and a lower overall profile, while the tough HDPE construction resists cracking, corrosion, and the chemicals found in RV waste systems. At 64 inches long and 44 inches wide, it's sized for full-size travel trailers and fifth wheels that need serious tank volume.
Whether you're replacing a failed tank or building out a custom rig, the Icon 12428 gives you dependable capacity you can count on for the long haul.
