Im looking at getting a brake controller for my F150. My job is going to buy a 20' cargo trailer to pull supplies in with my truck. The trailer is tandom axle and has trailer brakes on it.
What is the difference in the price of some of the brake controllers out there? I know some of them vary on how many axles they are made to work on but other than that, whats the difference in a $130 brake controller and a $70 brake controller?
Also, some of the higher ones are digital, what is it showing and is it important that it is digital?
