I see most people are attaching their roof baskets utilizing gutter mounts, my question is how much weight do you guys feel comfortable putting up there? I ask because I am looking at a roof top tent that sleeps four and weighs 160#. between the roof basket, my self, wife, and 2 small kids the weight is adding up. ideally we would have kids sleep in the car and the adults would sleep in the tent or the other way around. just not sure how much those gutters will hold. I have also looked into a cargo trailer but then the cost starts to get outa control.
