Don’t know about the ‘07 model, but everything I’ve seen from about 2016 to date, an HBA Brake Cam is required for towing with any GM vehicle. It is not a standard item (option from DRV) and I have no idea what it does. From their website:
* HBA Brake Cam (To be Ordered Special for Customers w/GM Trucks)
Best to check with DRV. Your Ford didn’t need that.
