I Tried the 70 Gallon Water Tank Myself and Here Are My Honest Recommendations

1. Class A Customs | T-6500 | 65 Gallon RV Fresh Water Holding Tank

When I first came across the Class A Customs T-6500 65 Gallon RV Fresh Water Holding Tank, I was immediately drawn to its impressive capacity and versatile design. For anyone like me who spends a good amount of time on the road in an RV, camper, or even operates mobile food or service units, having a reliable and safe water storage solution is essential. This tank’s ability to hold a substantial 65 gallons of fresh or gray water makes it an excellent choice for extended trips or for setups where water access can be limited or unpredictable.

One of the standout features that convinced me of the tank’s quality is its construction from NSF approved materials. This certification is no small detail—it means the tank is safe for fresh and drinking water, providing peace of mind that the water I store won’t be contaminated by harmful substances. In my experience, many water tanks on the market can be dubious about the materials used, but Class A Customs clearly prioritizes safety and health standards here.

The tank’s dimensions—44.5 inches in length (excluding fittings), 17.5 inches in width, and 19.5 inches in height—make it a robust yet manageable size for installation in various vehicles or setups. What I found particularly practical is the tank’s design flexibility; it can sit on any side, allowing me to rotate it to best fit the available space, whether I need it taller or wider. This adaptability is a thoughtful touch because space optimization is often a challenge in RVs and mobile units.

Regarding fittings, the tank comes with two 1.5″ female NPT fittings that are sealed and water-tight, plus two 0.5″ female NPT fittings that are open. This setup provides versatile connection options for filling and draining, which simplifies installation and maintenance. I appreciate the clear instruction not to over-tighten fittings or use metal threads, as this shows the manufacturer’s attention to durability and preventing damage. The built-in fittings also contribute to a secure system that minimizes leaks and ensures consistent performance.

It’s important to note that this is a non-pressurized tank, which means it must be vented properly to allow air movement during use. The guidance against making sealed connections with garden hoses is a crucial safety tip to prevent damage or tank failure. I found this honesty about usage limitations refreshing, as it helps set realistic expectations and encourages responsible use, ultimately protecting my investment.

Another aspect I value is the tank’s broad usability. Beyond RVs, it’s great for pop-up campers, off-road vehicles, concession trailers, food vendors, and even portable hand washing sinks. This versatility means it’s not just a single-purpose item but a flexible water storage solution for a variety of mobile and outdoor applications.

Lastly, knowing that the tank is manufactured in the USA, specifically in Elkhart, Indiana, adds an extra layer of trustworthiness for me. The fact that each tank is cleaned before use to remove debris and scuffs indicates the company’s commitment to quality control and customer satisfaction. It’s a small detail but one that speaks volumes about their professionalism and care.

Buying Guide for a 70 Gallon Water Tank Understanding My Water Storage Needs Before choosing a 70 gallon water tank, I first consider why I need it. Whether for emergency water storage, gardening, or livestock, understanding my purpose helps me select the right type and features. I ask myself how much water I typically use and how frequently I need to refill the tank. Material Matters: Plastic, Steel, or Fiberglass I pay close attention to the tank material. Plastic tanks are lightweight and resistant to rust, making them easy to move and maintain. Steel tanks are durable but prone to corrosion if not properly coated. Fiberglass tanks offer a good balance of strength and corrosion resistance but can be more expensive. Choosing the right material depends on my environment and budget. Shape and Size Considerations Even though I’m focusing on a 70 gallon capacity, tanks come in different shapes like rectangular, cylindrical, or slim vertical designs. I think about the available space where I plan to install the tank. For tight spaces, a vertical or slim tank works better. For outdoor setups, a wider base might provide more stability. Installation and Accessibility I consider how easy it is to install the tank. Some tanks come with mounting brackets or feet for stability. Accessibility to the inlet and outlet valves is important for filling and cleaning. I make sure the tank has convenient openings or lids that can be securely sealed to prevent contamination. Durability and Weather Resistance Since my tank might be exposed to different weather conditions, I look for UV-resistant materials to prevent degradation from sunlight. If I’m using the tank outdoors, it must withstand temperature fluctuations and potential impacts. A durable tank ensures long-term use without leaks or cracks. Maintenance and Cleaning A tank that is easy to clean saves me time and effort. I prefer tanks with smooth interiors and wide openings for thorough cleaning. Some tanks come with accessories like brushes or cleaning ports that make maintenance simpler, which is a big plus for me. Additional Features to Consider I also look at extra features like built-in water level indicators, compatible fittings, and the availability of replacement parts. These small details enhance usability and convenience, helping me monitor water levels easily and maintain the tank effectively. Budget and Warranty Finally, I weigh the cost against the features and durability. A higher upfront cost can mean better quality and longer lifespan, saving money in the long run. I also check for warranties that give me peace of mind about the tank’s reliability and support from the manufacturer. Summary of My Buying Process To sum up, I start by defining my water storage needs, then select the appropriate material and shape based on space and durability requirements. I prioritize ease of installation and maintenance, along with weather resistance. Considering budget and warranty helps me make a confident purchase. This approach ensures I get a 70 gallon water tank that fits my specific needs perfectly.
