Thule Roof Cargo Box Options
The list includes hard-shell roof boxes like the Pulse 2 L and Motion 3 XL. These models offer enclosed, weather-resistant storage for commuters and long trips. The Pulse 2 L features dual-side access, while the Motion 3 XL provides a low-profile, aerodynamic design for larger loads. You can also consider the Force 3 XL for secure, dual-opening convenience. For smaller needs, the Caprock Kit suits rugged adventures with compact dimensions. Soft options like the Interstate Bag provide lightweight, occasional storage that packs flat. Hitch-mounted carriers such as the Santu Box offer easy loading with rolling wheels. The GateMate Pro serves truck owners carrying bikes, though it is not a roof box. The Chasm 80L is a waterproof soft tote for gear organization, not a hard-shell alternative. Select based on your vehicle type and capacity needs.
Where Thule Fits Your Needs
Thule offers a wide range of storage solutions, from compact soft bags to large hard-shell boxes. The Pulse 2 L provides dual-side access for easy loading. The Motion 3 XL and Force 3 XL deliver ample space for long trips, with the Motion 3 XL featuring a low profile for better aerodynamics. You can also find hitch-mounted options like the Santu and Arcos Tilt Platform for versatile access. However, the list lacks models with interior lighting. The Caprock kit is extremely small, limiting it to tiny items. There are no standard large, single-side opening boxes shown here. You should choose based on whether you need roof or hitch mounting and the specific size of your cargo.
If you need workshop ventilation while loading gear, you can compare airflow ratings across the best box fans.
How to Choose a Thule Roof Box
-
Match Size to Gear
Start by measuring your largest items. The Motion 3 XL offers 90 inches of length for bulky gear, while the Pulse 2 L provides 81 inches for standard loads. Check the cubic footage if listed, as it indicates total volume. Larger boxes fit more but add wind resistance. Ensure your roof rack can support the added weight and length. Measure your vehicle’s roof width to ensure the box does not overhang excessively. Choose a size that holds your typical trip needs without excess bulk.
-
Check Opening Style
Decide how you want to load items. The Pulse 2 L and Force 3 XL feature dual-side opening, allowing access from either side of the vehicle. This is useful when parked in tight spaces. Single-side models require you to walk around the car. Consider your typical parking situation. Dual-side access adds convenience for frequent loaders. Verify the mechanism type, such as gas struts or manual latches. Ensure the opening direction matches your roof rail orientation for smooth operation.
-
Verify Mount Type
Confirm your vehicle’s attachment method. Most Thule boxes use roof mounts, attaching to crossbars. The Santu model uses a hitch mount, requiring a receiver tube. The Arcos is a hitch platform, not a box. Check your vehicle’s available mounting points. Roof mounts need compatible crossbars. Hitch mounts require a compatible receiver size, such as 1.25 inches. Ensure your vehicle supports the chosen mount type. Incorrect mounting can lead to safety issues or damage. Select the type that matches your vehicle’s hardware.
-
Assess Aerodynamic Profile
Consider the box’s shape and height. The Motion 3 XL has a low profile of 17 inches, reducing wind noise and drag. Taller boxes like the Chasm gear hauler are soft-sided and packable. Hard-shell boxes generally have rounded edges for airflow. A lower profile improves fuel efficiency and stability at high speeds. Check the height spec against your garage clearance. Ensure the box fits under low structures. Aerodynamic design matters for long highway drives. Match the profile to your driving habits and vehicle height.
-
Check Weight Limits
Review the box’s weight and your rack’s capacity. The Motion 3 XL weighs 68.6 pounds, while the Force 3 XL is 65 pounds. Soft bags like the Interstate weigh only 5.5 pounds. Your roof rack has a dynamic weight limit for driving. Subtract the box weight from this limit to find your usable cargo capacity. Do not exceed the rack’s static limit when parked. Heavy boxes increase strain on your vehicle. Distribute weight evenly inside the box. Check specs to ensure safe loading for your specific setup.
