Both the 20 gallon black water holding tank (EPI-1299) and the 22 gallon fresh water tank (Alpha VR182611W) are currently in stock at Elkhart RV Parts. You can order one of each now, and as a business account customer, you receive a 10% discount on your total order. Custom fittings installation is available; if you order 30 or more tanks, the manufacturer can install fittings directly, saving time and cost. For smaller orders, Elkhart RV Parts performs fittings installation in-house, typically on Fridays. Pricing after discount is $224.97 for the black water tank and $170.36 for the fresh water tank. Due to holiday production shutdowns, it’s recommended to place your order promptly to ensure timely delivery. If you need fittings installed, please provide the number of tanks and fittings per tank for an accurate quote, and a form for fittings placement can be provided.
