I am a 28 year veteran of long haul tractor trailer experience. I have never used electric brakes before, and have purchased a 2018 Atlas. I will be mainly pulling a travel trailer around BC, so it will be mountainous conditions. As I am used to air brakes, what are the differing factors when using electric brakes. With the 8 speed transmission, will I get any or much hold back in lower gears from the V6?
