I just decided to replace my old Hopkins proportional brake controller with the p3 after reading all the good reviews. I also want to be better informed on what's happening electrically with my brakes...
Yeah, I think the next step is to pull all 4 wheels and do a thorough inspection and see what I'm dealing with . The last thing I want is 33 feet of trailer pushing me through a red light. Or worse. Thanks for the input everybody.
