I had an engine shutdown problem in my vintage Newell coach, PPG have been a Detroit Diesel engine specialist for ever so I had the coach delivered to them. Brandee Hanson was the service adviser and Dave Mueller was my Detroit engine contact. They both performed exceptionally, diagnosing the problem and solved it in short order. While the coach was there I had the Chassis shop service and inspect the coach, another excellent experience. I am confident the coach is safe and totally roadworthy.
