MODULAR BYNATURE
WE HAVEYOUR BACK
Pull Up. Swing Out. Adventure On.
This is more than a tagline—it’s a way of life for those who live to escape the pavement.
With HitchFire, the journey doesn’t end when you park—it begins. Pull up to your favorite trailhead, campsite, beach bluff, or racetrack. Swing out our patent-pending dual arm and suddenly, you’ve got a fully functioning grill or cook station right at your tailgate—no tools, no hassle, no wasted time. It’s built to move with you, not slow you down.
LEVEL UP YOUR COOKING GAME
Whether you're grilling burgers in the backcountry or prepping coffee at a sunrise trailhead, HitchFire brings serious functionality to your outdoor kitchen. And it’s not just about convenience—it’s about trust. Our products have logged thousands of miles with our community, across deserts, coastlines, and mountain passes. The same grill you fire up in Moab is the one you’ll be using at the tailgate in Tuscaloosa.
Rugged, refined, and ridiculously easy to use—this is outdoor cooking done right.
Keep the Mess & Smell outside
With HitchFire’s hitch-mounted grills and cook stations, you keep the action (and the odors) exactly where they belong—outside. No more stinking up your ride with bacon grease or scrubbing pots in a cramped sink. Our systems give you the freedom to cook big, clean up fast, and get back to what matters.
Add an integrated sink basin, faucet hookup, and side prep surfaces, and you’ve got a full-blown kitchen in the fresh air. Sizzle, sear, and clean—without dragging the dirt and smoke back indoors.
