I recently purchased a used 2011 3500 cab chassis and when i went to pull my gooseneck which has electric over hydraulic brakes the truck doesn't have the option to choose the brake type and im confused by this because i have a 2011 3500 Laramie that has the electric over hydraulic option, so what im asking is this just a program thing that can be fixed at dealer or was this not a option untill later for the cab chassis. Anyone else run in to this
