I was advised by a Rack Attach technician that the 1600XT was the largest Thule box that would fit our new Highlander, but I had seen photos of the 1800XT box on another Highlander on a Toyota enthusiasts' forum and decided to risk it. Mounted on Thule RB53 Rapid Aero Bars and 450R Rapid Crossroad towers attached to the factory rails, the box has minimal but sufficient clearance to the rear-hatch spoiler with the hatch open. This will make a great camping box for our family.

Frequently Asked Questions

Below you will find a list of the most frequently asked questions for this product. If you need more assistance you can email a rack-install technician, or call us at: 1-888-440-5556

If you drive an SUV or van, probably not. Be sure to measure the total height of the vehicle with the Thule 687XT Atlantis 1800 Silver installed, and keep that information handy (on the inside of your sun visor is a great place). Running into your garage will, unfortunately, void the box's warranty.

While the weight limit of your roof rack may differ, cargo boxes can hold up to 165 pounds.

As long as your vehicle is equipt with the crossbars (side to side) then all of our cargo boxes will attach directly to the rack. If you have a rear hatch, make sure to measure how much room you have and compare to the box length to make sure the hatch won't hit the box when opening. If you don't have crossbars, you will first need to add those prior to adding in a cargo box.
