1. Class A Customs – T-0500 – One (1) 5 Gallon RV Fresh and Gray Water Holding Tank RV Concession

When I first came across the Class A Customs T-0500, a 5-gallon RV Fresh and Gray Water Holding Tank, I knew I had stumbled upon a product that could significantly enhance my outdoor adventures. Whether you’re a seasoned RVer, a concession trailer operator, or someone who simply enjoys the flexibility of off-road vehicles, this tank is designed to meet your diverse water storage needs seamlessly. The thought of having a reliable storage solution for both fresh and gray water truly elevates the convenience of any journey.
One of the standout features of the T-0500 is its construction from NSF approved materials. This certification means the tank is safe for storing fresh and drinking water, which is a huge plus for anyone concerned about water quality. Knowing that I can confidently use this tank for both fresh water and gray water storage, without compromising safety, gives me peace of mind during my travels. The dimensions of the tank, measuring 17 1/2 inches in length, 7 inches in width, and 9 1/2 inches in height (not including fittings), make it compact enough to fit into various setups, whether in an RV, a pop-up camper, or even a portable hand-washing sink.
Another aspect that I find particularly beneficial is the versatility of the tank’s placement. The ability to rotate the tank to change its height or width opens up numerous options for installation. I appreciate products that adapt to my needs rather than forcing me to adapt to them. This flexibility is especially crucial when space is at a premium, as it often is in RVs and concession trailers. The average thickness of 7/32 inches ensures durability while maintaining an overall lightweight profile, making it easy to handle and install.
The built-in fittings of the T-0500 further enhance its user-friendly design. With one 1.5″ female NPT fitting that is sealed and watertight, along with three .5″ female NPT fittings, the tank is ready for a variety of plumbing configurations. However, I do want to emphasize the importance of following the instructions regarding the fittings. Using plastic connecting fittings instead of metal ones helps prevent damage to the threads, which is an easy mistake to avoid. This attention to detail in the design reassures me that Class A Customs has prioritized user experience and durability.
It’s also crucial to note that this tank is non-pressurized and must be vented for proper operation. This feature may seem like a minor detail, but it’s a significant safety consideration. I appreciate that the instructions are straightforward, advising against making a sealed connection with a garden hose to prevent any risk of explosion. It’s these safety features that highlight the thoughtful engineering behind the T-0500, making it a reliable choice for anyone needing extra water storage.
In summary, the Class A Customs T-0500 5 Gallon RV Fresh and Gray Water Holding Tank is an excellent investment for anyone who appreciates quality and practicality in their outdoor equipment. It’s a product that genuinely caters to the needs of RV enthusiasts, food vendors, and anyone looking for effective water storage solutions. If you’re considering enhancing your outdoor experiences or ensuring you have adequate water storage, I strongly recommend giving this tank a try. It’s built with care, offers versatility, and is designed to make your adventures that much smoother.

As someone who has navigated the world of water storage, I can attest to the importance of having a reliable 5-gallon water tank. These tanks are versatile, whether for household use, camping, or emergency preparedness. Understanding their features and functionalities will help you make an informed decision.
