Service manager is the biggest douchbag rush mechanics are trial and error mechanics that means they fix something , hope its the right part , if not they come and get you on the freeway in 110* weather and take it back to fix something else . Stay away if you just own your truck and your not under a lease if you have a lease your screwed Service manager is pussy too likes to talk to truck drivers like he talks to his kids So you need to set him straight It's not worth the hassle he cries to my boss and says he was OFFENDED!!! By my TONE of voice are we truck drivers or are we running a ladies nail shop stay away
