It should fit all 2008 and up models, as it came of a dual battery optioned 2010 Sprinter cargo 2500.
This is a higher duty alternator that typically came with vans that had the dual battery setup, so ideal for campers.
and this is more expensive than a regular 180A one. (the option cost about $900 with Mercedes)
It has just been rebuilt by Brighouse Auto Electric, in Richmond, BC: have the bill stating what was done.
I myself come to the island for weekends regularly, so I could bring the alternator with me free of charge, or have it shipped at your cost if interested.
