We have a diesel pusher motorcoach with Cummins engine, Allison transmission on a Spartan chassis. We have used Boyer Trucks twice for service issues and they are absolutely wonderful to work with! Dan Nynas is our service manager and John(not sure of title) are the two we worked with the most. John had worked many years for the Duluth Transportation Authority in Duluth, Minnesota and has many years of experience with buses and Allison. When we went to drive unit out of storage, we had no forward. It took John all of 5 minutes to diagnose the problem as our touch pad. This is a very capable, honest dealership, that could have worked all day on it and we would not have known the difference. Highly recommend this place for any diesel pusher RVer with engine, chassis or transmission issues!
