I just purchased a 2016 4x4 3500 Advanced RV conversion (in Ohio). I took it to Georgetown Mercedes to get the Texas inspection done - online scheduling, same-day service available. They were on-time for the appointment and very friendly. They have a new, separate building for Sprinter service. The Sprinter Manager introduced us to their head Sprinter tech, and both took the time to answer our questions. They had us back on the road very quickly. I hope not to need them again before our first service, but I am very pleased with my interactions with them so far.
