When you’re looking to replace the black water holding tank that shipped with your RV, you will want the highest quality aftermarket part for this item. After all, this tank holds the sewage from your recreational vehicle trip, so you absolutely do not want leaks or ruptures here, which would cause a significant mess. If your OEM black water storage tank is starting to show its age, you can replace it successfully with the RecPro 40 Gallon RV Holding Tank. Our aftermarket black water tank consists of high quality plastics, which will stand up to the stress of being full of water and sewage while you’re driving over rough roads in rural areas. We put these tanks through precise testing processes, giving our customers further comfort in the quality they are receiving. Because this tank holds 40 gallons, you will be able to camp longer before needing to visit a sewage station. And with the 3-inch outlet tube, emptying the black water tank doesn’t take much time. It has dimensions of 40” x 36” x 8.5”. We use tight manufacturing tolerances with this replacement holding tank, which ensures it will fit tightly into the same spot as the OEM black water tank. A precise fit reduces the chances of leaks, because the replacement tank will not shift out of position after installation. At RecPro, we take pride in our ability to deliver the highest quality of aftermarket RV parts.
