11.5 vs 12 Cu Ft Specs
Storage capacity
The primary difference between these two Garvee models is their internal volume. The 11.5 cu ft Dual-Side Hard Shell Box offers 11.5 cubic feet, or 326 liters, of storage space. The 12 Cu Ft Dual-Side Hard Shell provides 12 cubic feet, equaling 340 liters. This adds 0.5 cubic feet, or 14 liters, of extra room in the larger model. For most road trips, both sizes handle standard luggage well. However, if you are packing bulky items like large suitcases or camping gear, the additional space in the 12 cu ft version helps. It allows you to fit more without stacking as high. You should measure your typical load to see if that extra volume matters.
External dimensions
Both carriers share the same footprint on your roof rack. Each model measures 54.3 inches in length and 31.5 inches in width. This consistent width ensures they fit standard crossbars on most cars, SUVs, and vans. The key difference lies in height. The 11.5 cu ft model stands 11.4 inches tall, while the 12 cu ft version is 13.4 inches tall. That 2-inch increase in height is what creates the extra storage volume. The taller profile of the 12 cu ft model may slightly affect your vehicle’s clearance in tight garages or low parking structures. Check your garage height if you plan to store the box indoors when not in use.
Load capacity
Both the Garvee 11.5 cu ft Dual-Side Hard Shell Box and the Garvee 12 Cu Ft Dual-Side Hard Shell share the same maximum load capacity. You can safely carry up to 135 pounds in either carrier. This limit applies to the total weight of your luggage and gear. It is important not to exceed this weight, as it can affect vehicle handling and safety. The identical load rating suggests that the structural integrity of the ABS shell is similar in both models. You should distribute the weight evenly inside the box to maintain stability while driving. Always check your vehicle’s roof rack weight limit as well, as it may be lower than the box’s limit.
Weight
The empty weight of the carriers differs slightly due to the size variation. The 11.5 cu ft model weighs 37 pounds. The 12 cu ft model is slightly heavier at 39 pounds. This two-pound difference is negligible for most users and will not significantly impact your vehicle’s fuel economy or handling. Both boxes are constructed from durable ABS material, which keeps them relatively lightweight compared to aluminum options. The slightly lighter 11.5 cu ft box might be easier to lift onto the roof if you are doing it alone. However, the 12 cu ft model’s extra weight is minimal and should not be a deciding factor for you.
Opening mechanism
Both models feature a convenient dual-sided opening system. This allows you to access your gear from either the driver’s side or the passenger side of your vehicle. This feature is useful when parking on narrow streets or in tight spots where you cannot open the trunk. Each carrier includes two keys and two straps for security. You must ensure one side is locked while opening the other side to maintain stability. This mechanism is identical on both the 11.5 cu ft and 12 cu ft versions. You will not notice any difference in ease of use or locking mechanism between the two models. It is a standard feature for both hard-shell carriers in this line.
Which Garvee Roof Box Fits You
You need maximum cargo volume
The 12 Cu Ft model offers 12 cubic feet of storage, which is 14 liters more than the 11.5 Cu Ft version. This extra space comes from its taller 13.4-inch height compared to the 11.4-inch height of the smaller box. Both share the same 54.3-inch length and 31.5-inch width, so the taller profile provides more vertical room for bulky items without increasing the footprint on your roof rack.
You prefer a lower profile
The 11.5 Cu Ft model stands 11.4 inches tall, making it slightly lower than the 12 Cu Ft alternative. This reduced height can help maintain a lower center of gravity and may improve aerodynamics slightly. It still provides 11.5 cubic feet of capacity and fits all vehicles with roof racks. If you prioritize a sleeker look or have height restrictions, this slimmer design is the practical choice.
You want the lighter carrier
The 11.5 Cu Ft box weighs 37 pounds, while the 12 Cu Ft version weighs 39 pounds. The 2-pound difference makes the smaller model easier to lift and install on your roof rack. Both use durable ABS hard shells and include dual-side opening mechanisms with keys and straps. If you handle the box frequently or have back concerns, the lighter weight offers a tangible benefit.
