How alternatives compare to Geardeck
Thule Motion 3 XXL Roof Box
The Thule Motion 3 XXL Roof Box shifts your storage from the hitch to the roof. It offers a massive 95-inch length and 20-inch height, providing significantly more volume than the 17 cubic feet of the Geardeck. You lose the convenient slide-out feature that clears SUV hatches, but you gain aerodynamic efficiency and easier access to the rear of your vehicle without moving the carrier. This option suits families or adventurers who prioritize maximum capacity over rear access convenience. The larger footprint requires a roof rack, whereas the Geardeck mounts directly to a hitch receiver. You should choose this if you need to haul bulky gear and do not mind roof mounting.
StowAway Max 16 cu ft Hitch Cargo Box
The StowAway Max Swingaway Hitch Cargo Box provides 16 cubic feet of capacity, which is slightly less than the Geardeck’s 17 cubic feet. It uses a swingaway design rather than a slide-out mechanism. This allows you to pull the carrier to the side to access your trunk or hatch, similar to the Geardeck’s function but with a different motion. It mounts to a 2-inch hitch receiver. The StowAway is a solid choice if you prefer a side-swinging action over a linear slide. It offers comparable rear access solutions for hitch-equipped vehicles. You might pick this if you want a proven swingaway alternative with similar capacity and hitch mounting convenience.
Yakima EXO SwingBase with GearLocker Cargo Box
The Yakima EXO SwingBase with GearLocker Cargo Box offers 10 cubic feet of storage, which is notably smaller than the 17 cubic feet of the Geardeck. It combines a swingaway base with a cargo box for compact hitch storage. This setup is ideal for drivers who prioritize rear access and do not need massive volume. You give up significant storage space for a more compact profile. The swingaway feature allows you to access the rear of your vehicle without removing the carrier. If you have a hitch receiver and only need to store smaller items, this is a practical alternative. It suits those who value convenience and compactness over raw capacity.
ENROAD XL Slim Roof Box with Solar Panel
The ENROAD XL Slim Roof Box with Solar Panel is a roof-mounted solution, unlike the hitch-mounted Geardeck. It features dual-side opening for convenient access and includes a solar panel for charging devices. This option is ideal for tech-focused travelers who need on-the-go power. You lose the hitch mounting and slide-out clearance, but you gain roof storage and solar charging capabilities. The hard shell design offers secure, keyless entry. This carrier suits SUV, truck, and van owners who want dual-side access and power solutions. Choose this if you prefer roof mounting and value integrated technology over the slide-out convenience of the Geardeck.
