Hey, Srt4runner, thank you so much for the fast reply, and all the information you provided, as well as the photo, because that’s the first actual profile photo I’ve seen of a 4Runner with the Motion XT XL size mounted.
So, what made you go with the aftermarket crossbars? We’re you afraid that the OEM crossbars wouldn’t be stiff enough, and allow too much movement?
I read on here that some people had issues with the factory bars being too low/flex too much and the box clamps would scratch the roof paint
I have read posts on forums where some people have used the factory Toyota crossbars with the Motion XT XL and not reported any issues.
But others have said that the stock Toyota crossbars are too low and not stiff enough, which caused issues such as flutter at highway speeds (since the box has to be mounted so far forward to clear the hatch spoiler when opened), the clamps contacting the roof (because the factory Toyota crossbars are so low), and the aft part of the box making contact with the sharkfin antenna (again, because the factory Toyota crossbars are so low).
It sounds like using aftermarket crossbars may be a way to dodge these problems completely, since they’re stiffer and stronger than the factory Toyota crossbars, and also sit higher. This was my reasoning
It’s just that they’re so expensive.
The set you have - the Thule 7503 Aeroblade Edge - isn’t that set around $500 by itself?
I paid around $380 for the set which is still pricey, but I go buy the rule of buy once cry once. And I dont have to spend money fixing my paint from scratches. Im sure if you look around you can find a deal on the box and the bars but who knows given the current supply chain issues with everything. You can always look for used as well. Either way the box gives you extra storage without having to spend more money on a bigger vehicle.
