Just wondering if they are an asset or a liability, thanks.
What is this Box you mention? thanks in advance.i just took a first road trip with the bars and a cargo box. Good news is noise is less than most cars when the bars are installed. I couldn't even tell they were on the highlander. With the box installed there was a little noise but less than on other cars.
The bad news is mileage took a rather sizable hit with the roof box installed, about 20%. More so than on other cars. It's possible that I was unlucky with heavy winds and rain but regardless, I was surprised.
