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

When I first came across the Class A Customs T-2000 20 Gallon RV Fresh Water Tank, I immediately recognized it as a practical and versatile solution for anyone needing reliable water storage on the go. Whether you’re an RV enthusiast, a pop-up camper user, or even operating a concession trailer or portable handwashing sink, this tank offers a robust and safe option to keep your water supply organized and accessible. The fact that it is manufactured by Class A Customs, a reputable company based in Elkhart, Indiana, adds a layer of confidence in the product’s quality and durability.

One of the key features that stood out to me is the tank’s material. It’s made from NSF approved materials, which means it is safe for fresh and drinking water storage. This is a critical factor for anyone who relies on their RV or camper for clean water, as it ensures no harmful chemicals will leach into the water supply. The tank’s dual-use capability—suitable for fresh or gray water—makes it extremely flexible depending on your specific needs. I appreciate that versatility because it gives me the freedom to use the tank exactly how I want, whether for clean water storage or as a gray water holding tank.

The dimensions and design of the tank also caught my attention. Measuring 32.5 inches in length (excluding fittings) and 11.75 inches in both width and height, this tank is compact enough to fit in various spaces but still offers a generous 20-gallon capacity. What I find particularly clever is the ability to position the tank on any side, allowing me to rotate it to change its height or width depending on the space available in my vehicle or setup. This flexibility is something that not many tanks offer and it can make a big difference when working with limited room.

Regarding installation and maintenance, the tank includes built-in fittings—two 1.5-inch female NPT fittings that are sealed and water-tight, plus two 0.5-inch female NPT fittings that are open. The instructions about carefully handling these fittings, especially avoiding over-tightening and using plastic threaded fittings instead of metal, show the company’s attention to detail and care for long-term durability. Knowing these specifics in advance helps me feel confident I won’t damage the tank during installation, which is often a concern with aftermarket components.

I also appreciate the safety considerations highlighted about the tank being non-pressurized. The requirement to vent the tank properly and avoid sealed connections with a garden hose is crucial information. It shows that the tank is designed with realistic usage scenarios in mind and that the manufacturer is transparent about how to avoid potential damage or hazards. This honesty helps me trust the product more and reduces the risk of misuse.

From a practical standpoint, this tank shines as an excellent extra water storage solution. Whether I’m heading out on a long road trip in my RV or running a food vendor cart that needs portable water access, the Class A Customs T-2000 tank meets those needs nicely. The cleaning process before shipping—removing any debris or scuffs—also speaks to the company’s quality control, ensuring I receive a tank that’s ready for immediate use without additional cleanup.

It’s large enough to hold a substantial amount of water but still manageable for various uses, from camping to emergency preparedness. Material Matters to Me The material of the tank is crucial because it affects durability and safety. I looked for tanks made from food-grade plastic or stainless steel to ensure the water stays clean and safe for drinking. Plastic tanks are lightweight and affordable, while stainless steel options offer better longevity. Size and Dimensions Fit My Space Although the capacity is fixed at 20 gallons, the physical dimensions can vary. I measured my intended storage area carefully to make sure the tank would fit comfortably without wasting space or being difficult to access. Portability and Handling Since I sometimes need to move the tank, features like handles or a design that makes lifting easier were important. A lightweight tank with sturdy grips helped me carry and transport it without strain. Ease of Cleaning and Maintenance I prefer tanks that are easy to clean because water tanks can develop algae or bacteria if neglected. Wide openings or removable lids allow me to reach inside for thorough cleaning. Also, I consider how simple it is to drain and refill the tank. Compatibility with Accessories Depending on my needs, I sometimes attach pumps, spigots, or filtration systems. I made sure the tank had standard fittings or ports to accommodate these accessories without complicated modifications. Durability and Weather Resistance Since I store my tank outdoors occasionally, it must withstand varying weather conditions. UV-resistant materials and sturdy construction help prevent cracking, fading, or damage from exposure to sun and cold. Price vs. Value I balanced cost with quality. While it’s tempting to go for the cheapest option, investing a bit more in a reliable, durable tank pays off in the long run by avoiding leaks or replacements.
