The bottom line: this combo is best for users needing a matched fresh and gray setup with multiple ports and seamless construction, because the tanks are rotationally molded from durable polyethylene and include essential fittings for typical RV installations. The reviewer found the set practical for replacement or OEM fitment, and the non-pressurized design and vent requirement are straightforward for standard plumbing layouts.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-size combo:\u003c\/strong\u003e Includes both a 30 gallon and a 42 gallon tank so installers get fresh and gray capacity suitable for many small to mid-size RVs and trailers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e Rotational molded polyethylene and one-piece seamless design reduce risk of blow-outs, stains, corrosion, or rust compared with multi-piece tanks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard connections:\u003c\/strong\u003e Each tank ships with one 1.25 in water fill inlet and three 3\/8 in NPT connections to simplify common hookups and fittings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-pressurized design:\u003c\/strong\u003e Tanks are vented rather than pressurized, which matches typical RV freshwater and gray water plumbing and eases installation of vents and fittings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBPA free:\u003c\/strong\u003e Fresh water storage is made with BPA-free material, offering reassurance for potable water in mobile kitchens and campers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe combo pack is ideal for RV owners, camper builders, concession trailers, and food trucks that need both fresh and gray water capacity with reliable, seamless tanks; contractors replacing OEM tanks will appreciate the range of ports and standard inlet sizes.
