I just took delivery of a 2021 Tracker 195 TXW with drum brakes on the trailer. The delivery guy said I would have to use the surge brake lockout pin when backing up. I have the 7 pin so I thought he might be wrong thinking I had the electric reverse lockout. Now I read the documentation and it says I MAY have free backing brakes on the trailer. Can anyone tell me what kind of brakes I have? I was able to back into my driveway which has a slight incline without using the lockout pin.
