As with all my vehicles I will perform all preventative maintenance and most repairs on my new (to me) 2006 E350. I need to know where I can find what is included in the "A, B, or C" or whatever they are called that the dealer would check if I were to allow them to perform maintenance. I have performed some searches but so far have come up with nothing usable.Thanks...I used to spend all me time on the diesel forum it will be good to get some new ideas from the gas side of the world
