Many dealers do offer mobile. That said for firmware updates, some are reluctant to perform them via the mobile service, as the Ford setup updates ALL modules for which there's an update when doing so, which could take significant time with some models.
The dealership my brother works at doesn't perform firmware updates via the mobile service, or that's what he indicated. His example was an F150 they had to leave updating overnight, connected to a 12v supply/battery maintainer. (It took 8 1/2 or so hours for the truck to perform all the updates). There's also a chance an ECM issues prevents the update from being applied, which on rare instances may cause the ECM to fail during the update process. (Their system does test the ECM before attempting to apply the update).
