Thule Motion 3 XXL Alternatives: 4 Similar Picks Compared

How these options differ

StowAway Max 16 cu ft Hitch Cargo Box

The StowAway Max 16 cu ft Hitch Cargo Box uses a hitch mount instead of roof rails. It measures 26 inches long and 23 inches wide, making it much smaller than the 95-inch Thule Motion 3 XXL. This compact size sacrifices volume for practicality. You gain rear hatch access without removing the box, thanks to its swingaway design. It fits drivers who prioritize easy access over maximum storage space. The hitch mount also keeps the cargo lower to the ground. You do not need to lift heavy items onto a roof. This option is ideal if your vehicle has a receiver and you frequently need to load gear from the ground.

Yakima EXO SwingBase with GearLocker Cargo Box

The Yakima EXO SwingBase with GearLocker Cargo Box is a hitch-mounted solution with 10 cubic feet of capacity. It is significantly smaller than the Thule Motion 3 XXL, which offers XX-Large volume. This unit measures 10 cu ft and mounts to a receiver. It provides secure storage for moderate gear loads. You get rear hatch access without removing the platform. This is a good choice if you have a hitch receiver and need a compact, secure option. You give up the large footprint and aerodynamic roof profile of the Thule. The Yakima system is better for users who value security and easy access over hauling bulky items. It fits well with smaller vehicles or those with limited roof space.

ENROAD XL Slim Roof Box with Solar Panel

The ENROAD XL Slim Roof Box with Solar Panel offers a dual-side opening hard shell design. It mounts on the roof like the Thule but includes a solar panel for charging devices. This tech feature is unique among traditional roof boxes. The ENROAD is an XL size, which is smaller than the Thule Motion 3 XXL XX-Large model. You gain biometric security and flexible access from both sides. You sacrifice some storage volume for these modern features. This option suits buyers who want tech integration and dual access. It is best for those who prioritize charging capabilities and secure entry points over maximum cargo space. The hard shell design also offers a different aesthetic and protection style compared to the wing-shaped Thule.

Let's Go Aero Geardeck 17 Cu Ft Slide-Out

The Let's Go Aero Geardeck 17 Cu Ft Slide-Out uses a hitch mount with a slide-out mechanism. It measures 50 inches long and 28 inches wide, which is shorter and narrower than the Thule Motion 3 XXL. This design solves clearance issues for rear doors on SUVs and RVs. You get waterproof storage and integrated lights in a hitch-mounted package. The slide-out feature allows you to access gear without opening the rear hatch. You give up the roof-mounted aerodynamics of the Thule. This option is best for drivers who must clear rear doors or need ground-level access. It is ideal for those who prioritize functional access over maximum volume or roof stability. The 80-pound weight is a factor for hitch compatibility.
