The T-5500 increases capacity to 55 gallons while maintaining NSF-approved materials for fresh or gray water storage. It is designed to be used in RVs or concession setups where space allows for a longer form factor. The tank measures approximately 37.5 inches in length with a width around 19.5 inches and a height near 17.5 inches, enabling versatile placement. As with other Class A Customs models, it includes two 1.5″ female NPT fittings and two 0.5″ fittings, with care instructions to avoid over-tightening to protect the fittings. Suitable for installations that require reliable, potable water storage with flexible mounting options.

Buying Guide: Key Purchase Considerations And Comparisons
Capacity vs. space: Larger tanks provide longer run times between fills but require more space. Measure storage compartments and consider whether you need a single large tank or a set of smaller tanks for different water types or zones in your vehicle.
Material and safety: Look for NSF-approved or BPA-free materials when storing drinking water. The material should resist cracking and be suitable for potable use. Confirm that fittings are watertight and rated for the expected pressure in an RV system.
Fittings and compatibility: Check the number and size of built-in fittings (commonly 1.5″ NPT and 0.5″ NPT) and ensure compatibility with your plumbing connectors. Fittings should be easy to access and not prone to leaks when tightened correctly.
Durability and mounting: Tanks designed for mobile environments should tolerate vibrations and temperature changes. Tanks that allow rotation or multiple sitting orientations help fit irregular spaces. Look for thickness in the 7/32″ range as a baseline for durability, with notes about manufacturing tolerances.
Maintenance and cleaning: Consider tanks that are easy to clean and inspect. Some models are designed for simple disassembly or have clear access points for cleaning and sanitizing before use.
Compliance and safety certifications: NSF approval, IAPMO standards, and other certifications are indicators of safety and reliability for potable water storage. When storing drinking water, these certifications are particularly important for long-term use in mobile environments.
Price-to-capacity balance: While not listing prices here, assess the total value by weighing capacity, materials, durability, and installation flexibility. A higher upfront cost may be justified by longer service life and easier maintenance in demanding travel scenarios.
