I think someone mentioned that every Pilot truckstop is a Freightliner repair center?
Even if that were true (and I don't think it is), just because a business can repair M2s and FL50s, doesn't mean they can take on a light duty vehicle like a Sprinter.
Close Rubbing, in short:
Take care of a Sprinter and it won't leave you stranded.
Fail to take care of it - failure to learn way more than you probably knew about your Astro - and you're begging the universe to toss lengthy down time and hefty repair bills your way.
The longer story:
It's harder to find Sprinter repair expertise than it is to find Chev Astro repair expertise by a very long shot.
Astros out number Sprinters by scores, maybe 100s to one.
I'm a drummer and I drive a Sprinter.
The last few bands I've been in haven't taken to the road for more than a three day weekend (we're old). I can tell you that these people -
http://www.bandago.com/ - make a living renting their Sprinters to bands for touring, so it's not impossible to make it work.
I'm comfortable with my 2007 Sprinter and if I had the opportunity, I'd take it on tour, but I know more about my 2007 Sprinter than most people know about their favorite pet. I wouldn't recommend a newbie buy a 2007/2008/2009 Sprinter band touring.
You posted in T1N talk, so I suppose you're considering a 2002 to 2006 Sprinter.
The T1N generation is more fuel efficient and less complicated, is less computer-dependent but - and this is me - I can't say I'd recommend a T1N for touring either.
If you have a problem, it's harder to find qualified help than it will be for a Detroit alternative.
In the US, too many shops can't execute an exhaust manifold (OM612 recall) replacement properly.
The people that get the most out of Sprinter ownership know more than the average person, can execute basic (and PROPER!) maintenance rituals and repairs on their own. They come here when they encounter conditions they'd not expected or want to venture further into the realm of "professional" grade repairs.
If that's you (or even if it's not you), start learning.
