If I am taking my coach to a place that services commercial trucks I expect to be low priority. If I am going to the neighborhood garage or dealership, I expect to have an appointment and for them to meet it. Of course we all know if parts are needed we are then put to the back of the line. Loosing two or three weekends of camping sucks. That's why I try to do most of my own work.
