2009 Tiffin Phaeton Engine Rebuild

Our 2009 Phaeton has a Cummins ISC 8.3 needs to have hte engine rebuilt. Cummins gave me an estimate of $66,000 and a reman engine is $78,000. Sounds ridiculous. Anyone have an experience with this?
  • Sounds awfully high. Googling shows rebuilt long blocks at under $20,000. Hard to believe it would take that difference in labor to replace it. Shop around.
  • It's expensive but what is wrong? Some issues can be fixed w/o engine removal. And probably some shops don't want to do any repairs w/o removing the engine so shop around.

    AFAIK Cummins has a set number of hours for a repair and a higher hourly rate for RVs. Justified based on engine access or we don't really want this job.
