I had a great experience with GTS Roadside Service. These guys are very fast and professional. Their ETA was accurate, and they arrived exactly when they said they would. They changed my starter on a Freightliner in 2 hrs even in harsh winter weather outside! What I really appreciated is that they don't overcharge — their prices are very reasonable, especially for roadside truck repair. Honest, reliable.
Best experience I could've imagined after a breakdown. They kept in contact with me during the whole process. The mechanic even picked me up at the hotel during a snowstorm. Went out of his way to get an aftermarket part for my truck and did the repair in a timely manner. Would definitely call them again. Thanks again!
Had issues with regen on truck. Had another company come out before these guys and they wouldn't do anything — sounded like lack of experience. Then I had these guys at GTS come out and had my driver driving down the road within an hour. Great service and customer service — highly recommend!
