Hey Al, I grew up in Vista. I now live in Escondido. The only places I have heard of that work on diesels are in Hemet and San Jacinto. My brother found one in Vista. I don't know if he is off of Sycamore or Rancho Sante Fe. He works on Mercedes. I don't know if he works on trucks. PM me and I can get you his number from my brother.
