1. Class A Customs | T-7500 | 75 Gallon Fresh Water Holding Tank

As someone who frequently engages in outdoor activities, I can truly appreciate the value of having a reliable water storage solution. The Class A Customs T-7500 Fresh Water Holding Tank has caught my attention for several compelling reasons, making it a strong contender for anyone in need of a practical and safe water storage option. With a generous capacity of 75 gallons, this tank is ideal for various applications, from RVs and pop-up campers to concession trailers and portable handwashing sinks. If you’re someone who spends time in the great outdoors or operates a mobile food business, this tank could significantly enhance your experience.

One of the standout features of the T-7500 is that it is manufactured from NSF approved materials, ensuring that the tank is fresh and drinking water safe. This is a crucial point for me, as I want to ensure that the water I am using is not only adequate in quantity but also safe for consumption. Knowing that the materials have passed stringent safety standards gives me peace of mind, especially when I’m filling the tank with fresh water for my family or customers.

The dimensions of the tank—50.5 inches in length, 17.5 inches in width, and 19.5 inches in height—provide versatility in how I can position it. The ability to rotate the tank to change its height or width is a practical touch that allows for flexible installation, whether I’m placing it in an RV or a trailer. Moreover, with an average thickness of 7/32 inches, the tank is sturdy yet manageable, which is an essential factor when considering the transport and storage of such a large item.

Another great feature is the built-in fittings. The tank includes two 1.5” female NPT fittings that are designed to be water-tight, which is a must for preventing leaks. Plus, the inclusion of two 0.5” female NPT fittings provides additional options for connection, allowing me to customize the setup according to my needs. However, it’s worth noting that caution is required when handling these fittings; over-tightening can lead to damage, so I appreciate the guidance provided by the manufacturer on using plastic threaded fittings instead of metal ones.

It’s also important to highlight that the T-7500 is a non-pressurized tank, which requires proper ventilation during use. This might seem like a minor detail, but it’s crucial for ensuring the longevity and effectiveness of the tank. I find the recommendation to use a fill dish or gravity process for filling the tank to be a sensible approach, minimizing risks associated with direct sealed connections that could potentially lead to dangerous situations.

Lastly, I’m impressed that Class A Customs manufactures this tank in the USA, specifically in Elkhart, Indiana. Knowing that I am supporting a local business while investing in a quality product adds an extra layer of satisfaction. Additionally, the company takes the time to clean each tank prior to shipping, ensuring that it arrives ready for use without any debris or marks from the manufacturing process. This attention to detail reflects a commitment to quality that I greatly admire.
