Install takes about 30 minutes for the cross bars but they feel quite sturdy once attached to the rails. I have not loaded a cargo box on top but I have no reason to believe it wouldnt be sturdy/stable. You can hear some slight whistling sounds once the car gets to around 70 mph but that is no biggie. Quality product.
