I have a 2018 Merceds Sprinter.
Anyone with a MB needs to know towing is very very easy. NO BRAKE CONTROLLER NEEDED. Save all the angst. There is a little gizmo developed last year about the size of a flashlight that plugs
in between the pin connector on the car and the trailer connector. Simply plug it in and go. Takes all of 10 seconds and they work amazingly well. All lights work, it shows the amount of brake pressure on
your smart phone. Genius!!! I got it from eTrailer. I just sold my trailers last week and have 3 of these goodies I'll sell cheap. The model number is Curt Code: C51180. They are $229 and deletes the need
for a brake controller. I have 3 I'll sell for $100 as I no longer need them. All three like new. Email me if interested. Rick
