Just the right size
Shopped quite extensively before selecting this particular unit. I had specific size requirements on the top of my sprinter van, and this one fit perfectly. Installation was straightforward and the fit on my roof looks perfect. I like the fact that it opens from both sides, although I use one side more than the other. It really finishes the attic space of our home.
Good box and easy to use
Good box for a good bag storage and easy to use, also good design and quality!
Please change the owners manual!!!!
This cargo box is great, but the owners manual is the worst I’ve ever seen for ANY product!!! There are pages and pages of drawings/graphics, but drawings alone are not always clear and helpful. I have no idea what some of them mean! It wouldn’t take much more effort to add a sentence or two to explain the instructions or warnings that go along with the graphics/illustrations and it would be extremely helpful!
Great rooftop cargo hauler.
I purchased the Thule Force 3 M to so that I could pack more stuff in my vehicle when travelling. It works great! It is easy to install. It attaches securely to my crossbars. It is convenient to load and unload because both sides open. It lock has a lock on it, which is easy to operate, and it provides security for all the stuff I pack in it. Overall, I am happy with my purchase.
Rooftop carrier
I bought this a while back for traveling, and have yet to use it. I have a Toyota Highlander and the rack system was perfect for this addition. I love the fact that it opens from both sides and I was able to install on my own.
Ready to Go!
Roomy and so convenient to use - love that it opens from both sides! Easy to install, great quality!
