1. Choose the Correct Rooftop Carrier First

If you are looking for something to carry a lot of items, you should go for a larger roof cargo carrier. Roof cargo carriers are usually available with eight cubic feet of storage space to more than 22 cubic feet of storage space. If you want to carry a lot of sports equipment like skis, snowboards, fishing rods, or suitcases with your cargo carrier, you should buy the cargo carrier that comes with 20 or more cubic feet of storage space that can carry all of your items comfortably.

Because surely your car’s trunk comes with a heavier weight carrying capacity than the roof of your car.

If you just want to carry suitcases with your cargo carrier, then you can also consider buying a rooftop carrier basket; depending on the size of your suitcases, you will be able to carry two or more suitcases with this cargo carrier.
