You probably know this but not all TB service quotes cover the same level of service. Before I left the vehicle, I would ask for a detailed written work estimate with a list of part numbers they intend to replace and compare that to other quotes. Some will provide the basic minimum (or less), while others do the extra preventive maintenances which takes more time and expense.
