RecPro Fresh & Gray Water Holding Tank Combo Pack (30 & 42 Gallon)

RecPro’s combo set contains two rigid holding tanks designed for fresh and gray water storage. The package is NSF approved and made in America, with pressure-tested tanks for reliability in mobile setups. While not a bladder, these tanks provide durable, static storage capacity ideal for longer trips or mobile concessions where stable, clean water storage is required. It is recommended to ensure complete sanitation prior to use and to verify compatibility with vehicle mounting options.
RecPro Fresh & Gray Water Holding Tank Combo Pack (21 & 30 Gallon)

Another RecPro option in this group provides two smaller-capacity tanks (21 and 30 gallons) that offer modularity for multi-vehicle fleets or limited-space applications. The set is TEI certified to IAPMO standards, and the manufacturer notes the importance of cleaning tanks before use. These tanks are best suited for applications where a blend of capacity and compact footprint is needed, and where multiple tanks can be staged for different water types or uses.
Class A Customs | 41 Gallon Fresh Water Holding Tank RV

Class A Customs offers a 41-gallon fresh water holding tank crafted for RVs and concession vehicles. Made from NSF-approved materials and designed for both fresh and gray water storage, this tank measures 71 inches in length and provides a consistent storage solution for mobile water needs. The design includes four fittings concentrated at one end, simplifying installation in tight spaces or along truck bed interiors. It’s a solid choice when rigid tank durability and straightforward mounting are priorities.
Buying Guide: Key Purchase Considerations
- Capacity needs: For “250 gallon” targets, prioritize high-capacity options such as the 200-Gallon bladder or larger rigid tanks, then consider modular setups to reach similar totals.
- Tank type: Bladder tanks save space and are highly portable but require careful sealing and pump access. Rigid tanks provide durability and easy mounting but occupy more space.
- Material and durability: Look for UV-resistant, food-grade, or NSF-certified materials, especially for potable water use. PVC-coated fabrics offer lightweight flexibility; rigid tanks often use robust plastics designed for vehicle mounting.
- Mounting and space: Measure truck bed clearance, corner access, and mounting points. Foldable bladders excel when space is at a premium; rigid tanks work well with dedicated mounting brackets.
- Fittings and compatibility: Check inlet/outlet diameters (DN25, DN20, etc.) and ensure hose connectors match your pumps and valves. Consider filtration or sanitation options if using potable water.
- Maintenance and sanitation: Some tanks require pre-use cleaning or TEI/IAPMO certification. Plan for cleaning procedures, especially for multi-use or food-truck applications.
- Portability and handling: For foldable bladders, assess handle rings and pack-down size. For rigid tanks, evaluate weight when full and the ease of installation/removal.
- Warranty and service life: Durability claims vary; prioritize brands with long service life and clear warranty terms, particularly for recreational or emergency outdoor use.
