A home away from home isn't complete if you're worried about running water. This could be as simple as getting some dishes done or taking a long, hot shower. That's where your water tank comes into play, but what if it's starting to break down? Don't worry; be happy you found Factory RV when you did. Our Water Tank Combo will have everything up and running smoothly in no time. This combo features a 16-gallon and 21-gallon water tank, giving you peace of mind when you need water, whether hanging out at the campground or making plans for long road trips. Our water tanks are rust- and corrosion-resistant and made with high-grade polyethylene, making them ideal for mobile and outdoor environments. Built with ⅛" thick walls, these tanks are designed to withstand pressure, vibration, and long-term use on the road without compromising structural integrity. For hassle-free installation and integration, each tank includes a 2" inlet with a ⅞" internal diameter and ½" outlets, making it compatible with standard RV plumbing setups.
