Hi Justin, I have a 2015 TRD Sport double cab with this exact same noise. It's been at the deeler for over a week now. This is the 3rd time I've taken it in. The service manager said it is related to cross winds, however, they have not been able to fix it yet. It's very frustrating. They did provide me a rental car at no cost, but it's not the same as my truck. Hoping some others may have a fix for this. In the mean time, I'll update what my dealer in Merritt Island FL comes up with. The noise I hear is at high way speeds usually around 75 - 80 when it's windy. Other times it does not make any noise unless you run it up to about 95 lol.[/QUOTE
