In the US Mercedes Sprinter vans are used exclusively by very affluent people so it doesnt dilute the brand there.

I think that's true as a personal vehicle. But you'll see them driving around with ladders, pipes, etc. on them as direct competitors to the Ford E-Series. You definitely don't see the Ford vans turned into luxury RVs though!

No idea how popular they are, but they certainly exist.

And also lots of the existing Amazon van fleet.
