I just wanted to say that the people at OC diesel in Orange County, Ca are the most helpful people i have met in a long time. They helped me out big time. Truck wouldn't pull my 48' trailer passed 35mph and shook like the motor was about to fly apart. They took it in after hours figured out what it was and fixed it the next day no problem. Will deff deal with them if plan on making any purchases or need any work done. Thank you OC Diesel.
