My truck was an easy fix that he turned into a nightmare from unskilled techs ripping at it.

FAS diesel is the only shop we will take our trucks to at Creamer Construction. Dan and the guys got our 6.0 running better than ever after a previous shop could not properly diagnose the problems. FAS is an honest and reliable company and we won’t go anywhere else with our trucks.
