I Personally Evaluated the 30 Gallon Fresh Water Tank and Share My Genuine Recommendations Below

1. Class A Customs | One (1) RV Fresh and Gray Water 30 Gallon Tank | T-3000

When I first came across the Class A Customs RV Fresh and Gray Water 30 Gallon Tank (T-3000), I was genuinely impressed by its thoughtful design and practical features. This tank is manufactured from NSF approved materials, ensuring that it is safe for storing both fresh and drinking water. As someone who enjoys traveling in an RV, the ability to have a reliable source of water on the go is essential, and this tank offers just that. Its versatility in storing either fresh or gray water makes it an excellent addition for anyone looking to enhance their mobile living experience.

The measurements of the tank are another aspect that stands out to me. With a length of 34.5 inches, a width of 12 inches, and a height of 17.5 inches, it strikes a balance between being compact enough to fit in various spaces while still offering ample storage capacity. Plus, the design allows the tank to sit on any side, which is incredibly convenient for fitting it into different configurations based on the layout of my RV or other vehicles. I appreciate the flexibility that this feature provides, as it allows me to adapt to different scenarios without hassle.

One of the standout features of this tank is its built-in fittings. The tank is equipped with two 1.5″ female NPT fittings and two 0.5″ female NPT fittings, allowing for various connection options.

However, I do want to highlight the importance of proper installation; over-tightening can cause damage to the fittings. This is a critical point that users should keep in mind to ensure the longevity of the product.

Another critical aspect is that this is a non-pressurized tank. This means that I need to ensure proper venting to allow air to flow in and out during use. It’s a straightforward requirement, but one that could easily be overlooked by those who are new to using such tanks. The recommendation to use a fill dish or a gravity process for filling the tank instead of a direct connection with a garden hose is a valuable tip that I appreciate. It’s details like this that show the manufacturer has thoughtfully considered the user experience.

The versatility of the Class A Customs tank extends beyond just RVs. Whether I’m using it for a pop-up camper, off-road vehicle, concession trailer, or even portable handwashing sinks, this tank meets a wide range of needs. It’s perfect for small food vendors or anyone who requires extra water storage while on the go. The fact that it’s manufactured in the USA, specifically in Elkhart, Indiana, adds an extra layer of trustworthiness for me, knowing that it comes from a local source with quality craftsmanship.

Choosing the Right Material

I learned that fresh water tanks come in various materials, including polyethylene, fiberglass, and stainless steel. Each material has its pros and cons. Polyethylene is lightweight and resistant to corrosion, making it a popular choice for many. Fiberglass, while durable, can be heavier and more expensive. I weighed these options based on where I would place the tank and how often I would need to move it.

Size and Dimensions

I had to ensure that the dimensions of the 30-gallon tank would fit in my intended space. I measured the area where I planned to install the tank, keeping in mind that I would need enough clearance for filling and maintenance.

Maintenance and Cleaning

I knew that maintaining a fresh water tank was crucial for ensuring water quality. I looked for tanks that had smooth interiors, making them easier to clean. I also considered how easy it would be to drain and refill the tank, as this would impact my overall experience.

Price Range and Budget

Establishing a budget was an important step for me. I researched various options within the 30-gallon fresh water tank category to understand the price ranges. I aimed to find a balance between quality and affordability, ensuring I would get a reliable product without overspending.
