3. Class A Customs | T-4000 | One (1) RV Fresh Water 40 Gallon Tank, Grey Water

As someone who has spent considerable time using RVs and exploring the great outdoors, I can confidently say that having a reliable water storage solution is a game-changer. The Class A Customs T-4000 RV Fresh Water and Gray Water Holding Tank is a fantastic option for anyone in need of extra water capacity, whether you’re a seasoned RV enthusiast or just starting your journey into the world of mobile living. With a generous 40-gallon capacity, this tank offers ample storage for both fresh and gray water, making it versatile and practical for various applications.
One of the standout features of this tank is that it’s made from NSF-approved materials, which means it is safe for fresh and drinking water. This is an essential consideration for anyone looking to ensure their water supply remains clean and safe. Knowing that I can use this tank without worrying about the potential for contaminants gives me peace of mind, especially during those long road trips or camping excursions when access to clean water can be limited.
The tank’s measurements—39 1/2 inches long, 13 inches wide, and 18 inches high—make it adaptable to various spaces. What I appreciate is the ability to rotate the tank to change its height or width, allowing me to maximize my storage options in different vehicles such as RVs, pop-up campers, off-road vehicles, concession trailers, and even portable handwashing sinks. This flexibility is particularly beneficial for those who have different setups or who may be using the tank in various settings.

Using plastic connecting fittings instead of metal is a smart move to protect the threads and maintain integrity over time.

Instead, using a fill dish or gravity process for filling the tank is a much safer approach, and I appreciate the manufacturer’s clear guidance on this.

Buying Guide for Dechlorinator for a 40 Gallon Tank
Understanding the Importance of Dechlorination
When I first started my aquarium journey, I quickly learned that dechlorination is crucial for maintaining a healthy environment for my fish. Chlorine and chloramine are commonly found in tap water, and they can be harmful to aquatic life. Using a dechlorinator helps to neutralize these chemicals, ensuring that my tank water is safe for my fish and plants.
Types of Dechlorinators
In my experience, dechlorinators come in various forms, including liquid, powder, and tablet options. Liquid dechlorinators are often the most popular choice due to their ease of use and quick action. Powders and tablets may require a bit more preparation, but they can be cost-effective for larger tanks. I suggest considering which form fits best into my routine.
Active Ingredients to Look For
I always check the active ingredients in a dechlorinator before purchasing. Common ingredients include sodium thiosulfate, which effectively neutralizes chlorine, and other compounds that target chloramine. It’s essential for me to ensure that the product I choose effectively removes both chlorine and chloramine, as this is vital for my tank’s ecosystem.
Dosage and Application
Understanding the dosage is critical for me to avoid any mishaps. Most dechlorinators come with clear guidelines on how much to use based on tank size. For my 40-gallon tank, I always make sure to follow the manufacturer’s instructions closely. Over-dosing can lead to unwanted chemical imbalances, so I take my time measuring the correct amount.
Compatibility with Other Products
Before buying, I also consider how the dechlorinator interacts with other products I use. Some dechlorinators may not be compatible with certain medications or water conditioners. I always read labels carefully to avoid any adverse reactions that could harm my aquatic friends.
Storage and Shelf Life
I pay attention to the storage requirements and shelf life of the dechlorinator. Some products may have specific storage conditions, while others can be kept at room temperature. Knowing how long the product lasts helps me plan my purchases better, preventing waste and ensuring I always have a reliable supply on hand.
Cost and Value
Finally, I evaluate the cost versus the value of the dechlorinator. While it might be tempting to go for the cheapest option, I’ve learned that sometimes investing a bit more can lead to better quality and effectiveness. I look for a product that fits my budget while still providing the safety my fish deserve.
In my experience, choosing the right dechlorinator for my 40-gallon tank involves careful consideration of several factors. From understanding the importance of dechlorination to evaluating types, ingredients, and compatibility, each step is essential. I always aim to create the best possible environment for my aquatic pets, and a good dechlorinator is a vital part of that process.
