I do not think many owners realize that Fords going down a hill on cruise control or ACC that the truck applies the service brakes including the trailer brakes. This could lead to overheating the trailer brakes without the driver realizing it. I am not sure if the others GM and RAM are the same now. I sure miss my 2015 RAM's exhaust brake going down passes and hills(always had nice cool service brakes) on my yearly commute to AZ and back to Wa.
It seems to me that the computer calculates brake temperature using speed and brake line pressure and will give a warning before the brakes get hot. Although I don't like to rely on the computer to apply my brakes without knowing what is going on I think it does function in a fairly responsible manner. When the brakes are applied the transmission downshifts to bring the engine revs fairly high .... if another brake application is necessary it will downshift further. When it does apply the brakes, it stabs the brakes slowing the truck down a bit and then releases them (it does not constantly apply brake pressure). If the auto EB function is used instead of cruise control, it downshifts fairly aggressively and then allows the engine to rev to the red line to make maximum use of the EB before applying wheel brakes.
