You won't get very far if you don't have a properly functioning water tank. Washing dishes, taking a bath or shower, or even spring cleaning means having access to fresh water. Like everything in your RV, it's only a matter of time before you see wear and tear on the water tank. Whether you're replacing or upgrading, you've come to the right place. Factory RV's 20-gallon Water Tank will be the perfect upgrade for your RV. This water tank is designed for potable or gray water, making it ideal for RVs, campers, trailers, or custom water systems. When you're looking for a water tank, you're looking for something high-quality that will last for years. That's why our water tank is constructed from high-density, heavy-duty polyethylene with ¼" thick walls for maximum durability, impact resistance, and long-term performance. We want to provide you with a customizable, flexible fit for your vehicle. That's why this product is a blank tank, allowing you to customize the fittings as you desire. Or, if you prefer, we can include the fittings so you can utilize them for nearly any plumbing configuration.
