1. Class A Customs | T-2000 | One (1) RV Fresh Water 20 Gallon Tank, Grey Water

As an avid RV enthusiast and someone who enjoys spending time outdoors, I’ve always been on the lookout for reliable and efficient water storage solutions. That’s why I was thrilled to discover the Class A Customs T-2000, a 20-gallon fresh or gray water holding tank. This product has completely changed my perspective on managing water resources during my adventures. Let me share my insights on why this tank is a fantastic choice for anyone in need of additional water storage, whether for RVing, camping, or even food vending.

First and foremost, the tank is manufactured by Class A Customs, a reputable name in the industry known for quality and durability. The fact that it is made from NSF approved materials gives me peace of mind, knowing that the tank is safe for fresh and drinking water storage. This is especially important for those of us who prioritize safety and health while on the road. With the T-2000, I can confidently store water that I can use for cooking, cleaning, or even drinking, which is a major plus!

When it comes to measurements, the tank boasts a compact design with dimensions of 32.5 inches in length, 11.75 inches in width, and 11.75 inches in height. This makes it easy to fit in various spaces within my RV or camper. I love that the tank can be positioned on any side, allowing me to adjust its height or width according to my specific needs. The average thickness of 7/32 inches provides a sturdy structure, ensuring it withstands the rigors of travel. Plus, the minor variations in size due to the manufacturing process are negligible, which I appreciate.

One feature that stands out is the built-in fittings. The T-2000 comes with two 1.5-inch female NPT fittings that are sealed and water-tight, along with two 0.5-inch female NPT fittings. I found it easy to work with these fittings, but I do recommend following the guidance to avoid over-tightening, as this can lead to damage. Using plastic threaded fittings instead of metal is a smart choice to ensure longevity. This attention to detail in the design gives me confidence that I can install the tank without any issues.

Another important consideration for any water tank is its functionality. The T-2000 is a non-pressurized tank, which means it must be vented to allow air in and out during use. I found this aspect particularly useful, as it prevents any mishaps during filling. It’s a good reminder to use gravity-based filling methods, which have always worked well for me. Whether I’m filling it with fresh water or using it for gray water storage, I appreciate the straightforward approach to filling and venting.

This water tank is versatile, making it perfect for a variety of applications. Personally, I use it for extra water storage in my RV during long trips, but it’s also an excellent choice for pop-up campers, off-road vehicles, concession trailers, and even portable handwashing sinks. This adaptability means that whether I’m on a family camping trip or running a small food stall, I can rely on the T-2000 to meet my water storage needs efficiently.

Lastly, I can’t overlook the fact that this tank is proudly manufactured in the USA, specifically in Elkhart, Indiana. Knowing that it’s made in a clean warehouse environment gives me confidence that it’s produced with care and quality in mind. It’s always great to support local manufacturing while ensuring that I’m getting a top-notch product.
