Pack more for big trips with an extra large capacity roof box from Thule. The roomy design is light enough to lift, installs quickly on factory or aftermarket crossbars, and can clear a shark fin, antenna, or the hatch when positioned and measured correctly. Just remember the added size needs storage space off the vehicle, and you may notice a bit more road noise on the highway.
Plan space to store the box when it's off the car. Expect some reduced gas mileage and added road noise. If the box opens from one side, mounting it slightly to that side on a tall vehicle helps access. Interior tie-downs vary; arrange cargo so the lid closes and latches cleanly before locking.
Yes, installation is quick and straightforward. The box is light enough that some people lift and mount it solo in about 5-10 minutes. Use the included clamps and confirm they're fully tightened during a walk-around. On taller vehicles, a step ladder helps, and shifting the box to one side can make loading easier.
They can keep gear protected when properly latched. On long trips through rain and heat, contents arrived in perfect condition with zero water damage inside. Make sure the latches fully engage before locking; the lock won't turn unless they do. If a lock housing gets damaged, a locksmith may be able to remove the cylinder when parts aren't available.
It can, but check your bar position and clearances first. Make sure the box sits far enough forward that the hatch opens without obstruction. Look at your antenna or roof fin location; some setups clear it, while others require removing or bending a whip-style antenna. If your bars are fixed, verify the spread and that the clamps can reach your crossbars.
Yes, as long as you have round, square, or aero crossbars. Many OEM cross bars work well—verify your crossbar spread and that the clamps fit your bar shape. Do a quick test-fit to confirm the box clears the hatch and doesn't interfere with any antenna or fin.
