Designed and manufactured 100% in Colorado, this lightweight aluminum tank is engineered for both the daily commuter who wants the freedom of extended range and the hardcore overlander pushing deep into the backcountry. Constructed from thicker 3mm 5052 aluminum with a Hammer Finish powder-coat, this system is built to withstand the harshest conditions - it has been thoroughly beat, bashed, and driven at elevations from 5,000 to 13,000 feet without failure.\n\u003c\/p\u003e\n\u003cp\u003e\n  One of the most thoughtfully integrated auxiliary fuel systems on the market, this tank preserves your Tundra's KDSS, Factory Air Ride, and Class 4 receiver hitch - no sacrifices required. It tucks above the bumper line for a virtually invisible, high-clearance profile and keeps all factory evap systems in place. Fueling is seamless: fill through your factory filler neck and both tanks fill simultaneously, so you never have to think about switching between them.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e18-Gallon Capacity:\u003c\/strong\u003e Adds significant range to your Tundra without the bulk of a bed-mounted solution.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3mm 5052 Aluminum Construction:\u003c\/strong\u003e Thicker-than-standard aluminum chosen for superior corrosion resistance and off-road durability.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHammer Finish Powder-Coating:\u003c\/strong\u003e A tough, attractive finish that resists chips, scratches, and the elements.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM Split Fill Point:\u003c\/strong\u003e Fills through your factory filler neck - both tanks fill simultaneously, requiring zero extra steps at the pump.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePreserves KDSS, Air Ride \u0026amp; Class 4 Hitch:\u003c\/strong\u003e Designed specifically so you keep every major factory system intact - no compromises.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Clearance, Invisible Profile:\u003c\/strong\u003e Tucks above the bumper line for a clean look and maintained ground clearance, critical for overlanding.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt-In Installation:\u003c\/strong\u003e Mounts to existing frame locations - almost no modification required.

This system was born out of real-world demands - tested on Colorado mountain roads, off-road trails, and daily commutes alike - giving you confidence that it will perform when it matters most. The nearly invisible installation means your Tundra looks factory-clean while quietly carrying an extra 18 gallons of range. Trusted by overlanders and off-road enthusiasts who refuse to compromise their factory systems, this tank is the gold standard for Tundra fuel capacity upgrades. Built entirely in the USA with premium materials and a complete installation kit, it's a long-term investment in freedom and capability. Whether you're managing a long haul between fuel stops or venturing where stations simply don't exist, this system gives you the range to go further with total peace of mind.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eView Product Specs\u003c\/strong\u003e\u003c\/summary\u003e\n\u003ctable border=\"1\"\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003cth\u003eTank Type\u003c\/th\u003e\n\u003ctd\u003eAuxiliary\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCapacity\u003c\/th\u003e\n\u003ctd\u003e18 Gallons\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eFuel Type\u003c\/th\u003e\n\u003ctd\u003eGasoline\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eFill Point\u003c\/th\u003e\n\u003ctd\u003eOEM Split (factory filler neck, simultaneous fill)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eWeight - Dry\u003c\/th\u003e\n\u003ctd\u003e25 Pounds\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eWeight - Wet\u003c\/th\u003e\n\u003ctd\u003e133 Pounds\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003e3mm 5052 Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eHammer Finish Powder-Coat\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eRelocate Spare Tire\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eRecommended Install Time\u003c\/th\u003e\n\u003ctd\u003e5 Hours\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCompatibility\u003c\/th\u003e\n\u003ctd\u003eToyota Tundra 2022 - Current\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCountry of Manufacture\u003c\/th\u003e\n\u003ctd\u003eUSA (Colorado)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eDelivery Estimate\u003c\/th\u003e\n\u003ctd\u003eStarting August 2026\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWill this auxiliary tank work with my Tundra's KDSS, Factory Air Ride, or receiver hitch?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eYes - this system is specifically designed to preserve all three.
