Being A Semi Trailer Mechanic , I learned to Diagnose and Solve any problems with the trailer. I learned how to reverse a Semi Trailer. I have great tool skills , good troubleshooting skills, and good knowledge about how a trailer runs. I mostly did suspension work so i can name all the parts and their functions. I can also replace parts needed , anything from Suspension Airbags to Suspension Bushings. I'm a Fast and Quick Learner.
