The Jeep Grand Cherokee (Chrysler body WK) as of 2007 came with the MB OM642 diesel, 3.0L diesel.
There are something like than 2 dozen variants of the OM642 engine listed in the Electronic Parts Catalog for MBUSA, LLC (epc.startekinfo.com) so a great number of vehicles fit your bill.
I believe 2006 Jeep Grand Cherokee's diesels had a 2.7 L, I5 OM647, but I'm not positive about that. I can only find two OM647 variants listed in EPC.
There are 8 variants of the OM612 family; one variant is found in the first T1Ns available in the US.
Daimler doesn't publish a matrix of chassis and engines, so it's on the the consumer to dig the info out of specs and journals like Motor Trend, maybe Consumer reports, maybe some other rag I can't think of at the moment.
If you really want an MB diesel engine, the shortest path to that is to get a bona fide MB product.
If you want a rebranded MB diesel engine, you're looking for diesel vehicles made in the Chrysler family of brands before Daimler divested from Chrysler/Cerebrus last year and before the Bankruptcy.
Good luck in your search.
