{"product_id":"1-2-2g2-4-gallon-extension-1","title":"RotopaX 1, 2 and 4 Gallon Extension — Container Stacking Kit","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe RotopaX 1, 2 and 4 Gallon Extension is the standard stacking kit in the RotopaX lineup — the one most builds need when running two containers on a single mount point. It lets you stack any combination of 1, 2, 2 GEN 2, and 4 gallon RotopaX containers together using a single Standard, DLX, or LOX pack mount, expanding your fuel or water capacity without adding a second mount location or taking up additional rack space.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe extension is built from anodized aluminum, consistent with the same hardware quality used throughout the RotopaX mounting system. Installation is straightforward: mount your base container to the vehicle using a standard pack mount, thread the extension into the center post, and stack the second container on top. The two containers lock together in a secure, rattle-free assembly that holds up through rough terrain and heavy vibration. The largest bottom container in the stack determines which extension you need — and for any combination of 1, 2, and 4 gallon containers, this is the right one.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe compatibility logic on extensions matters, and it is worth getting right before ordering. This extension is for stacking 1, 2, 2 GEN 2, and 4 gallon containers together. It does not work with 1.75 gallon containers — those require the 1.75 Gallon Extension. It does not work with 3 gallon containers — those require the 3 Gallon Extension. If you are unsure which extension your setup needs, the rule is simple: identify the largest base container in your stack and match the extension to it.\u003c\/p\u003e","brand":"RotopaX","offers":[{"title":"Default Title","offer_id":42563686596693,"sku":"RX-EXT","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/5868\/8853\/files\/RX-EXT1_6a9fdf79-3e85-4c2a-b589-8d442181c433.jpg?v=1780417568","url":"https:\/\/www.padoverland.com\/products\/1-2-2g2-4-gallon-extension-1","provider":"PAD Overland","version":"1.0","type":"link"}
