Our Waste Holding Tanks are a great solution for long-term RV living. Their spacious 300-gallon capacity allows you to extend the capacity of your black and grey water tanks. After a one-time installation fee, the monthly rental will save customers money, as we include twice a month service into the rental cost! Eliminate the hassle of hauling to an RV dumping site.
