2021 Sequoia TRD PRO Roof Rack dimensions

Going on a trip this summer and looking to see how big a roof rack basket I can put on the roof rack that comes on the TRD Pro. Anyone happen to know the length/width of the roof rack? quick and dirty I came up with something like 46x80 but doing it alone with a cheap tape measure, not sure how accurate I was. Going to be a group of 7 of us and my daughter needs a lot of medical equipment and supplies (using a tow hitch basket for 2 wheel chairs, one that folds and my daughter's zippie wheelchair). If it were only the 4 of us and just the zippie would take the tundra and not have any worries about storage but alas...

 

Just left town today so can’t help ya, but if max cargo is what’s needed look into getting a large platform rack for on top of the factory rack, or remove it and go full rack (front runner, victory, etc)
