If you’re looking for the perfect rooftop cargo carrier, it’s good to research them first so you get the best one for your needs. Most carriers are made to fit any type of vehicle that you might own, including sedans, minivans, SUVs, and even pickup trucks.
Does this mean that you can just run out and purchase a carrier without considering how it will fit once it’s installed? Of course not. In fact, one of the things that you’ll have to consider before making your purchase is the weight of that carrier once you get it loaded.
As a general rule, most cartop carriers can hold anywhere from 75 to 250 pounds of gear and equipment but that usually includes the weight of the carrier itself as well as the items inside of it.
You should also check with your car’s manual in case the vehicle itself has any special limitations. Otherwise, strict attention should be paid to whatever the manufacturer of the carrier recommends so the vehicle doesn’t get damaged.
If you’re curious about cartop carriers, both soft-shell and hard-shell, that can handle even the heaviest of items, below are some of the largest ones that will make you proud to own them.
