If Option A is non-responsive they may be hiding something. Options B and C, for all intent purposes, are equal. I have a 2012, 6.2L Raptor with 258,532 miles. The only major work I had done was Upper and Lower ball joints, which is to be expected given the miles. Routine maintenance is performed at regular intervals and the Raptor still runs strong. The Ford dealer where I had the ball joints replaced services two (2) Gen 1 Raptors each with over 300,000 and no major engine work. They are built tough for Baha runs and are over-engineered for daily driving.
