Thule Motion XT Rooftop Cargo Carrier
Thule industries have been at the forefront in the production of quality cars and outdoor accessories since 1964 when they introduced the Thule Roof Basket. It comes as no surprise one of their latest products, The 18 cubic feet Thule Motion XT Cargo carrier, is our best pick for the GMC Terrain.
The elegantly designed 84.5 by 36 by 17-inch roof box offers more than enough room for your camping gear and luggage for memorable outdoor adventures. The dual side opening mechanism offers easy access to your belongings, while the SlideLock system ensures the lid is securely closed during the entirety of your journey.
Adding weight on top of your vehicle raises the center of gravity, affecting your vehicle’s performance, especially when going off-road and negotiating corners.
To mitigate this, The Thule Motion XT has a lower profile design, and when properly mounted, it distributes the weight evenly on to the roof rack. A streamlined design ensures air resistance is significantly reduced, which will save you gas money at the pump.
Thule Pulse Rooftop Cargo Box
The Thule Pulse Roof Box makes it to this list because it delivers on quality, utility, and durability despite it being the most affordable. The roof box has a length of 76”, 33” wide, and a depth of 16.5”, which is big enough to fit up to 6 pair skis or 5 snowboards.
It offers you 16 cubic feet of cargo space while the maximum load capacity is capped at 110 pounds. Moreover, installation is pretty effortless as the box comes almost fully assembled, a few twitches, and you’re good to go in no time.
The lid opens from the passenger side, a distinctive feature of the Thule Pulse models that allows hands-free access thanks to the lid lifters stationed at both the front and back ends.
SecureLock technology integrates the Thule comfort key that can’t be removed from the central lock until all the locking points have been securely fastened. The Thule Pulse is perfect for hauling all your gear and still not leave a significant dent in your pocket.
INNO BRM665WH Wedge Cargo Box
Closing the ranks is the classy INNO Wedge Cargo Box. The roof box is painted white, first, to give it a gorgeous appearance and second, to prevent the cargo carrier’s interior from heating up in sunny conditions.
While the 56-pound roof box might have a smaller volume capacity than the other products, it has a tougher shell due to the more robust SPM injection technology used on its exterior. Other roof boxes use vacuum forming which is not as sturdy.
It is also compatible with most of the factory racks which makes installation very easy. Unlike the Thule Pulse Rooftop Cargo Box, it features a dual-side opening for faster loading/unloading your camping gear.
Lastly, this box can be adjusted back and forth, providing enough clearance for the GMC Terrain’s rear hatch to be fully opened.
It is paramount to know and work within the limits of your car’s roof load rating, usually provided on your vehicle’s manual. Exceeding roof load limits poses a safety concern not only for you but also for other road users.
The featured products are the best roof boxes for your vehicle as their load limits are all below the 175-pound roof load rating of the GMC Terrain.
