Hello. Just got a '21 Aviator a few days ago. I notice the max. recommended load capacity for the roof is 82 lbs. I had planned to get a Thule box for extra cargo capacity while traveling with the three kids. But the box I wanted (Motion XT Large) weighs ~40lbs. leaving only another ~40lbs. for cargo (i.e. clothes and whatnot).
Does anyone know if this limit is based on a structural limitation of the vehicle or if it's more of a center-of-gravity/handling/safety limitation? Anyone have experience carrying a bit more than the recommended amount?
