We have a 2022 MYP and will be installing the Tesla roof rack, all that's left is to pick out a roof box. It'll be for a family of 4 (2 adults, 2 young children, mostly snow trips to resorts for snowboarding). We are debating between the Thule Motion XT (XL?) vs Yakima GrandTour (16 vs 18?). Just wondering if people have experience with either product and would recommend one over the other if cost isn't a huge issue.
