some options....
1. As suggested, fellow TDR member. Get your filters from Cummins or Geno's.
2. Do you know of a local, private mechanic whom you can trust? Take your own oil and filter.
3. Not all dealers are totally incapable of doing this right. A local dealer did my first change... . didn't want to mess with the welded filter at the first change. They let me get right under the truck and hood and watch the whole process, plus they let me bring my own oil and filter. The kid was careful, helpful, and conscientious. Cost me $25 for labor. I've done my own since.
I would not go to a quick-lube, Wal-mart, etc. Talk about very high odds for incompetency.....
One of you Georgia TDR guys/gals step up for Dixie.....
