Upgrade your vehicle's wastewater system with the heavy-duty Icon HT176B-ED Holding Tank. Built stronger than standard RV tanks, this beast lets you rough it for longer without giving up on your personal comfort. The tank's central drainage makes emptying a breeze, while its space-saving design allows you to maximize interior room. Best of all, the tank can handle black water, gray water, or even a combination of both. That way, you can go wherever your free-wheeling spirit might take you without any worries.
