It wasn?
It wasn?t bad, very professional. My service person was great. The technical side of it, I wasn?t to sure about because the technician had to go back and do one job over. I turned my truck in on Thursday 28th and service wasn?t completed until Saturday 28th. A little long to me.

Once again, Vikki did a fantastic job of taking care of
Once again, Vikki did a fantastic job of taking care of me and my truck. I scheduled the 100K service for my truck, and then got a curveball that made keeping the appointment more of a challenge. Vikki was able to help me reschedule my appointment in a way that still aligned with my schedule. Vikki?s attention to detail, knowledge, and responsiveness give me confidence in services/repairs being done right the first time. Her care and understanding of how to take care of her customers makes DeMontrond the only place where my truck will be serviced.
