The 10 Gallon Tote-Along Drain Water Tank is designed to assist RV campers by transferring grey and black water from holding tanks on their RV into one of our tote tanks. This allows campers to stay at their site and eliminates the hassle of moving an RV. Five convenient sizes (5 to 30 gallons) provide a capacity for every need. All original Tote-Along come completely assembled and feature blow-molded polyethylene construction with quality zinc plated steel brackets throughout. This model includes a tow bracket and 5ft sewer hose. Extra-large heavy-duty wheels and standard bayonet fittings are also included.
