My husband recently bought an F350 diesel pickup. We take it to Dave Knapp for the routine maintenance and they do a wonderful job. They are very prompt with your appointment and the wait is never too long. My husband also recently had a minor problem with his truck and took it here to be fixed. They found the problem and fixed it and informed us it was covered under warranty (which we were not aware of). They even called us at home the next day to see if the truck was running okay. I feel that is great customer service.
