Transporting liquids securely is another area where this tank shines. Molded tie-down channels allow me to fasten the tank firmly with compatible saddle straps, which is vital when moving it in an RV or on a worksite.

Its 40-gallon capacity is substantial enough to meet a variety of watering needs, yet still manageable for transport and handling, making it a practical choice for both small and larger scale outdoor work.

One of the features that truly stands out to me is the translucent white poly construction. Being able to see the liquid levels inside the tank without opening it is a huge convenience. It saves time and guesswork, helping me monitor water availability at a glance, which is especially useful when I’m out in the field and need to plan my next steps efficiently. Additionally, the chemical-resistant material paired with fade-resistant UV protection means this tank is built to withstand harsh outdoor conditions without deteriorating quickly. This durability gives me confidence that the investment will last through seasons of use.

Portability is another key factor I appreciate. The tank is designed to be easily hauled on trucks, tractors, or trailers, making it a true “water system on the go.” This mobility means I can take water exactly where I need it, whether for irrigation, livestock, or cleaning tasks. The wide 6-inch cap facilitates easy filling, and the 2-inch drain with a molded 3/4-inch port that fits a standard garden hose is a smart touch for quick and mess-free draining.

This product isn’t just a typical stock tank; it’s truly multi-purpose.

I appreciate how it adapts seamlessly to both professional agricultural settings and creative everyday uses.

The durability of this tank really stands out to me. Made from structural foam, it resists weathering and cracking, which means it’s built to last through harsh outdoor conditions.

This is a crucial feature for anyone who needs dependable equipment that won’t fail after just one season of use.

One of the features that reassured me about the product’s quality is its leakproof design. The seamless construction eliminates worries about leaks or water loss, which is essential when you’re using it for water storage or livestock feed. Having a tank that doesn’t leak means less maintenance and less waste, which is a practical benefit that translates into savings and peace of mind.

The tank’s strong construction is another highlight. The stepped sidewalls resist bowing, providing added stability—a feature I find valuable especially when the tank is full and heavy.

4. Class A Customs | T-10000 | One (1) RV Fresh Water 100 Gallon Tank, Grey Water | Ribbed for Extra Support

When I first came across the Class A Customs T-10000 100 Gallon RV Fresh Water Tank, I was immediately impressed by its thoughtful design and versatile functionality. Knowing how crucial reliable water storage is for RV owners and other mobile setups, this product really stands out as a practical and durable solution. Whether you need a fresh water tank or a grey water storage option, this tank offers the flexibility to serve both purposes effectively.

One of the biggest selling points for me is the fact that the tank is made from NSF-approved materials, which means it’s safe for fresh and drinking water storage. This assurance is critical because I want to be confident that the water I or my family consume is stored in a clean, non-toxic environment. The ability to use the tank for grey water as well adds to its versatility, making it a smart investment for RV owners or anyone who needs a multi-purpose water storage solution.

The dimensions of the tank—50 inches in length (excluding fittings), 18 inches wide, and 26 inches tall—make it a compact yet capacious unit that fits well within typical RV storage compartments. I appreciate that the tank can be oriented in different ways, sitting on any side to change the height or width according to space constraints. This adaptability is a huge plus for me, especially when dealing with the often limited and irregular storage spaces in RVs or trailers.

Another feature I found particularly reassuring is the ribbed design for extra support. This structural enhancement ensures that the tank maintains its shape and integrity even when fully loaded, reducing the risk of deformation or damage during transit. Additionally, the tank’s thickness, averaging 7/32” with minor manufacturing tolerances, hints at a robust build quality that should stand up well to everyday use and rough road conditions.

Regarding fittings, the tank comes equipped with six 1.5″ female NPT fittings and two 0.5″ female NPT fittings. The fittings are sealed and watertight, though I was advised to remove the membrane carefully with a razor knife before use. The instructions to avoid over-tightening and to use plastic threaded fittings instead of metal threads show that the manufacturer prioritizes preventing damage and ensuring a long service life for the tank. It’s clear they want users like me to avoid common pitfalls that could compromise the tank’s integrity.

I found the non-pressurized design important to note. Since the tank must be vented for air flow, it prevents dangerous pressure build-ups that could cause tank failure. The warning against connecting a garden hose directly to the tank under pressure reflects the company’s commitment to user safety. I appreciate these practical recommendations because they help me avoid costly mistakes and increase the tank’s lifespan.

In terms of applications, this tank’s versatility really shines. Beyond RVs, it’s suitable for pop-up campers, off-road vehicles, concession trailers, hot dog carts, smaller food vendors, and portable hand washing sinks. This wide range of uses means that whether I’m on a road trip, running a mobile food business, or setting up a temporary wash station, the T-10000 tank can meet my water storage needs reliably.

Lastly, the fact that Class A Customs manufactures this tank in the USA, specifically in Elkhart, Indiana, gives me confidence in the quality control and craftsmanship behind the product. The company cleans each tank before shipment to remove any manufacturing debris, which shows attention to detail and customer care.

Whether for gardening, emergency preparedness, or even just collecting rainwater, the large capacity gave me peace of mind knowing I had plenty of water on hand.

Buying Guide for a 100 Gallon Plastic Tank

Understanding My Needs

Before purchasing a 100 gallon plastic tank, I first assess what I need it for. Whether it’s for water storage, chemical containment, or rainwater harvesting, knowing the intended use helps me select the right type of tank material and features.

Material Considerations

I look at the type of plastic used in the tank. Common materials include polyethylene and polypropylene, each offering different levels of durability and resistance to UV rays or chemicals. For outdoor use, I prefer UV-stabilized plastic to prevent degradation over time.

Shape and Dimensions

The shape of the tank matters based on where I plan to place it. Some tanks are vertical, which saves floor space, while others are horizontal and better for fitting under structures or in confined areas. I measure my available space to ensure the tank fits comfortably.

Features and Accessories

I check for useful features like threaded outlets, fill ports, and vent caps. These make installation and maintenance easier. Some tanks come with built-in handles or mounting brackets, which can be helpful depending on my setup.

Durability and Warranty

Durability is important to me because I want my tank to last for years. I look for tanks that have thick walls and come with a warranty, as this indicates the manufacturer’s confidence in their product.

Price and Budget

I compare prices among different brands and sellers but balance cost with quality. Sometimes paying a bit more upfront saves money in the long run by avoiding replacements or repairs.

Maintenance and Cleaning

I consider how easy it will be to clean and maintain the tank. Tanks with wide openings or removable lids make cleaning simpler, which is important for keeping stored liquids safe.

Environmental Impact

Lastly, I think about the environmental impact. Choosing a tank made from recyclable materials or one that is itself recyclable helps reduce waste. Also, a tank designed for rainwater harvesting supports sustainable water use.
