It's an interesting idea, but there's a business model consideration having to do with logistics. I imagine that a good percentage of emergency roadside repairs are coordinated through a nationwide planning service such as Good Sam. When summoned, Good Sam is going to tap its extensive network of approved providers. Whether or not a Sprinter-specific service is ever going to get called out for the most common ailments is questionable. And the lion's share of the cash flow (which makes a business viable) tends to derive from the most common ailments.
For instance, this provider that you've pictured has a tire change image on their Sprinter wrap. Certainly tire issues are among the most common, as I found out the hard way last summer (
thread). But it's not necessary to have Sprinter-specific service for those bread-and-butter issues.
