Is there a guideline where a ranger will be sent to you rather than drive to a service location? Can you request ranger service from about 115 mi. Out as I am?
You could request ranger service in the comments when scheduling the appointment. A real person reads the comments and will advise on whether Tesla can accommodate your request.
I had scheduled a service visit and they sent me a text that "This is something that can be handled by mobile. Would you like to change?" -- so if they can do it, they will change, but as @Lonestar noted, you can put a comment that it's preferred, too.
