The HitchFire Difference

Built different. On purpose.

ENGINEERED

Built for the Long Haul

Crafted from premium materials with zero corners cut — made to handle the road, the dust, the rain, and whatever else you throw at it.

PATENTED

Pull Up, Swing Out

Our proprietary dual swing arm gives you full access to your tailgate, so your gear is never in the way — just the way you want it.

MODULAR

Modular by Nature

From grills to cargo platforms, our modular system lets you use one swing arm for multiple products — giving you more ways to level up your adventures.

BACKED

We Have Your Back

Every product comes with a 2-year warranty and U.S.-based customer support from folks who actually care (and actually answer).

Our Story

Built by people who'd rather be outside.

HitchFire started in a Santa Cruz garage with one stubborn idea: you shouldn't have to leave real cooking at home. So we built a full-size grill that mounts to your hitch, swings out of the way on a patented dual arm, and fires up wherever the pavement ends.

Every product since — cargo platforms, camp kitchens, cook stations — runs on that same swing arm and the same promise: rugged gear, road-tested from the Rubicon to Baja, backed by a 2-year warranty and people who actually pick up the phone.
